Baldauff, Regis (September 2014) ‘Current Global Trends for Titanium Applications within the Chemical Process and Oil & Gas Markets' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Recent Global events and Catastrophes have created a Paradigm Shift in material Choices for decision makers within the Chemical Process and Oil and Gas Markets. Piping and Equipment manufacturers and large OEM’s have been tasked with designing components and systems that increase performance, improve life cycles and reduce risk. Titanium offers all of these with the correct design and application. With that said titanium products are facing increasing competition within this market space from products such as Fiberglas Reinforced Pipe (FRP), Duplex and Super Duplex Stainless Steel materials. Pricing should not be the only evaluation tool used for determining which product is the best material of choice. Safety and Performance characteristics are now at the top of list when it comes to the design criteria that is used within these Industrial Markets. This presentation will provide an overview of these current market conditions and why Titanium can provide solutions to these problems and provide superior performance over the long term.


Barnes, John E. (September 2014) ‘Titanium 3D Printed Treatment of Sleep Apnoea' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

A novel oral appliance for providing breathing assistance during sleep for the treatment of both snoring and sleep apnea has been developed by CSIRO researchers and Oventus Pty Ltd clinicians. Sleep apnoea occurs when the air passage in the throat becomes blocked during sleep and causes people to stop breathing. People can suffer hundreds of events per night and it is estimated that about 4% of men and 2% of women in the Western world have sleep apnea, but it could be as high as 14% of adults have the disorder. Left untreated, sleep apnoea can have serious and life-shortening consequences: high blood pressure, heart disease, stroke, automobile accidents caused by falling asleep at the wheel, diabetes, depression, and other ailments.

Additive manufacturing was used to enable the device relying on its ability to affordably provide a custom fit with a lightweight, comfortable device. A 3D scanner is used to map a patient’s mouth anatomy, and that custom design can be 3D printed in titanium, with a recess for the user's teeth with an opening to allow air from outside to be drawn in. The air passes through an airway on each side, and is directed into a posterior region of the mouth, bypassing issues with tongue and lower jaw position. In more severe cases, the opening to the outside can be connected to a continuous positive airway pressure machine, providing more comfort and increased patient compliance compared to a mask. Researchers moved into industrialisation, writing software that would automatically read a 3D scan result and morph a file in a database to meet the patient requirements.

This paper will share the experience of developing this technology and discuss the advantages/shortcomings of the potential growth in 3D printing in the bio-medical industry.


Bayne, Andrew (September 2014) ‘Titanium Revert in 2015' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

This presentation will examine the opportunities and challenges surrounding the titanium revert chain. The aerospace inventory overhang continues to wind down at a time where melt rates are increasing, driving a continued focus on “closing the loop”. Difficulties continue due to the growing geographical diversity of generation sites, and educating new sources on the importance of segregation and cleanliness. The industry is also experiencing supplier consolidations while scrap pricing is moving towards parity with sponge and alloy. Each of these phenomena will be discussed and the impact on the near-term and long-term future considered.


Bihlman, Bill (September 2014) ‘Global Supply Chain Trends' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Titanium can be viewed as a strategic commodity; thus, this industry’s health is of particular importance to both engine and airframe OEMs. This presentation will briefly address the various categories within the value chain. It will also explore significant developments over the past 5 years until present. It will discuss varied topics, such as sourcing from Russia, the impact of additive manufacturing, and the effects of vertical integration by the mills.


Birt, Aaron (September 2014) ‘An Analysis of the Mechanical Properties and Microstructure Resulting from Cold Sprayed Ti-6Al-4V' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

With the government and industry driven focus on new material systems and additive manufacturing, new processes for material consolidation techniques are constantly being developed. One such system, cold spray, bombards particles onto a substrate and induces bonding through particle deformation derived from the kinetic energy of the impact, all while remaining in the solid state. It has been successfully used in re-manufacturing and surface modifications. However, with the focus on near net shape manufacturing techniques coming to the fore, a shift towards bulk net shape materials created with cold spray has begun. Research presented here used the cold spray technique to consolidate martensitic Ti-6Al-4V powders at the highest kinetic energy levels possible in order to introduce the highest levels of deformation and work in the consolidated material. The resulting samples were tested for tensile strength, macrohardness, and microhardness. Microstructural features were analyzed with secondary electron microscopy and optical microscopy. The relationship between the level of work introduced to the system, microstructure, and mechanical properties will be discussed.


Bonini, Julius (September 2014) ‘Cleanliness Related to Post-Fabrication Processing of Additive Layer Manufactured Porous Surface' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Porous-layer coated titanium medical and dental implants have been the industry standard for several decades. Sintered-on wire or beads, as well as plasma sprayed titanium coatings, have been the most common methods for creating a porous surface structure for effective osseointegration in these devices. Each of these coating methods generates a unique porous structure and efficacious methods have evolved over the years to ensure cleanliness of the final device. The use of several new additive layer manufacturing (ALM) methods to fabricate implant devices with integrated porous surface structures has presented new challenges to achieving the required level of cleanliness in this industry. These new ALM methods, such as electron beam manufacturing (EBM), as applied specifically to titanium devices, create unique and complex porous surface structures that present considerable challenges for appropriate cleaning. These complex structures involve a combination of interconnected and closed cell porosity. Exposure to cutting fluids, cleaning fluids, solvents, blast media, grinding media, passivation solutions and many other chemical agents during processing presents several possible means of contamination. These potential contaminants tend to become entrapped in unique ways in these complex porous structures and need to be completely removed prior to packaging as finished goods. Images of the complex porous structures will be presented in both spatial and cross-sectional view via optical and scanning electron microscope (SEM) imaging.


Bruneau, Albert (September 2014) ‘Global Trends in Industrial Markets’ presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Hickton, Dawne S. (September 2014) Titanium in the Military: What About Tomorrow?’ presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

The changing nature of defense threats is driving a transformation in the systems and tools utilized to combat those threats. It is a transformation that is also raising new questions about the role of titanium as a strategic defense material. How is the new defense picture affecting use of titanium in the weapons and support systems of today and in the future? Is sequestration behind us? Should we count parts, not pounds? Mrs. Hickton will discuss these and related issues in the context of current U.S. and European defense budgets and the stresses felt in an era of austerity, juxtaposed against growing Chinese defense spending. She will also highlight how titanium has transformed from a strategic material whose value was measured in pounds, to an innovative material whose uses are far more varied and for which value is measured by its inclusion in sophisticated, advanced technology systems.

Honnart, Alain (September 2014) ‘Near Net Shape: From Dream To Reality' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Metalvalue is cooperating with a Swedish company Bofors Bruk AB (named as was the Alfred Nobel’s company: not surprising for a company located in the same city of Karlskoga) and its daughter company METEC Technologies AB to develop a new technology able to manufacture parts from a few ten grams to a few kilograms: the MMS SCANPAC™ process.

Developing a new technology takes time: from the first idea in 1996 to the last patent registered a few weeks ago (a total of 6 complementary patents), years have been spent in R&D, prototypes, pre-¬‐series, end user tests, etc. Now the process is operating and already used to supply alloyed steel, tool steel nickel alloy parts at full density with the same or better properties of forged products.

The same technology is used for titanium. The technology is environmentally friendly, no toxic binder, energy saving, material saving. The driver for its development is simply cost: it allows to make parts cheaper than the conventional route. The fact that they are metallurgically better (because they are made from powder) is just a plus. This cost saving comes from different factors: the powder itself is cheap because, despite the fact that the process can use ultra-¬‐high purity atomized powder it allows to get it at low price because it will use the left over from the production of additive manufacturing powder. In addition the manufacturing cost is inexpensive and parts are pressed at high speed. Products can easily be qualified for aerospace usage (due to the manufacturing steps ending with a low cost HIP operation).

All the experience already gained from manufacturing other metal parts, can be transferred to titanium. The SCANPAC- MMS process will contribute to develop volumes in titanium parts for many industrial applications.

Ivasishin, Orest (September 2014) ‘Fundamentals of Low Cost Titanium Hydride Powder Metallurgy' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Recently, an innovative approach in blended elemental powder metallurgy of titanium and titanium alloys was developed. Its key feature consists in using of titanium hydride powder instead of commonly used titanium metal powder what results in improved balance of mechanical properties due to lower residual porosity, lesser contamination and finer microstructure as compared to conventional titanium powder metallurgy. This paper is stressed on the results elucidating fundamental advantage of titanium hydride based powder metallurgy which consists in synergetic influence of specific compaction mechanism, activated sintering due to a sequence of phase transformations accompanying dehydrogenation, and reactions of surface located impurities with atomic hydrogen with a formation of volatile products leaving the compact through an open porosity network. Efforts to scale up this approach from laboratory experiments to commercial level capable to solve the cost- performance dilemma of titanium powder metallurgy are demonstrated.


Jackson, Christopher (September 2014) ‘Titanium Sponge Developments in India' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

The Kroll technology developed by Defence Metallurgical Research Laboratory (DMRL) is successfully transferred to Kerala Minerals & Metals Limited, Kerala, India for the establishment of the country’s first commercial facility for titanium sponge production with a starting capacity of 500 MT per year. The KMML titanium sponge production facility producing titanium sponge regularly in the batch size of 3.5-3.75 MT by the combined process technology demonstrated by DMRL. While several engineering improvements are being brought in during the regular production of titanium sponge at KMML, an elaborate product quality assurance and certification procedure is taken up by DMRL for using the titanium sponge for critical aerospace applications.

As part of the sponge quality assurance programme, large number of samples from randomly chosen production batches have been analyzed through chemical analysis, button melting and hardness testing. Industrial scale melts from selected sponge lots of size 1.75 MT have been made and taken for characterization of down stream processing through forging, hot rolling, extrusion and cold rolling etc. A number of titanium alloys such as Ti6Al4V and half alloy have been melted and processed for the manufacture of several mill products.

Kaneko, Michio (September 2014) ‘Photocatalytic Activity of Anodized Titanium Sheets under Ultra-violet and Visible Light Irradiation' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

A commercially pure titanium sheet precipitated TiC in surface the layer was fabricated by anodization in NH4NO3 and heat treatment in air. The fabricated sheet showed relatively high photocatalytic activity in 0.1M KI solution of just below the activity level of the P-25 particle made by Deguza Corporation. It exhibited photocatalytic activity in antifungal and antivirus tests under black light irradiation, and the high photocatalytic activity under black light irradiation is considered to be related formation of anatase type titanium dioxide and increase of surface area. It also showed photocatalytic activity under visual light irradiation, which, is considered to be attributable to the existence of carbon and nitrogen in titanium dioxide.

Samimi, Peyman (September 2014) ‘A Novel Tool to Assess the Influence of Compositional Variation on the Oxidation Behavior and Concurrent Oxygen-induced Phase Transformations of Binary Ti-X systems' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Authors: Peyman Samimi, David Brice, Yue Liu, Peter C Collins
Titanium alloys are generally described as having superior corrosion resistance at room temperature. However, at elevated temperatures, titanium suffers from poor oxidation resistance and consequently, loses its resistance to corrosion. This limits the service temperature of titanium in application to ~550°C. Although the high-temperature oxidation of Ti and Ti alloys has been a subject of several research efforts such studies however are often constrained to the composition of specific alloys and neither the mechanisms associated with evolution of oxide layers nor the effects of oxygen on the microstructure of the material are well-understood. To better explore the influence of composition variation on the oxidation behavior of the binary Ti-X systems, a novel combinatorial approach was adopted whereby a series of compositionally graded specimen, (Ti-xMo, Ti-xCr, Ti-xAl and Ti-xW) were prepared using an additive manufacturing approach, and subsequently exposed to still-air at 650°C. A suite of the state-of-the-art characterization techniques including scanning and transmission electron microscopy as well as atom probe tomography were used to assess, as a function of the local average composition: the structure and composition of the oxide; the oxide adherence and porosity; the thickness of the oxide layers; the depth of oxygen ingress; and microstructural evolution of the base material just below the surface but within the oxygen-enriched region.


Shidid, Darpan (September 2014) ‘Design and Manufacture of Patient Specific Jaw Implant using Selective Laser Melting' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

**CSIRO's 2014 Titanium Challenge Winner** **TITANIUM USA 2014 Best Master Dissertation Winner**

Osteosarcoma is an aggressive type of bone cancer, which often needs radical surgical treatment methods to contain the spread of the cancer cells. In this study, a novel method of designing patient specific orthopedic implant to assist in surgical treatment of osteosarcoma is studied. The implant design comprising of conformal lattice structure suitable to be manufactured using Selective Laser Melting (SLM), is proposed. The design process is automated using a custom developed algorithm to reduce processing time.

The generated designs are mechanically tested to validate the algorithm. The results show that structures with functionally gradient density can be adapted to reduce stiffness mismatch between the bone and implant. Proposed implant design is predicted to have significant impact on patient’s quality of life compared to conventional mass-produced orthopedic implants.


Sebastian, John T. (September 2014) ‘Application of Integrated Computational Materials Engineering to the Design of New High Performance' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Integrated Computational Materials Engineering (ICME) methodologies are effective tools to reconfigure the materials development process to meet specific properties and accelerate implementation of new higher performance alloys into demanding applications. New alloys, meeting specific properties to achieve desired performance goals, can be designed much more quickly and at lower cost than empirical trial and error methods. This is achieved at the design stage by specifying and developing the precise chemical composition and processing parameters of the alloy, using extensive thermodynamic and kinetic databases, advanced properties modeling along with ICME computational tools based on physics, and quantum mechanics.

QuesTek Innovations has applied its Materials by Design® approach to develop three new castable titanium alloys with strength and ductility characteristics similar to wrought titanium (e.g., wrought Ti-6Al-4V) and with greater strength and ductility over traditional cast Ti-6-4. The development of these alloys has been sponsored by a U.S. Army-funded Small Business Innovation Research (SBIR) program administered through Picatinny Arsenal, New Jersey.

Thomas, Craig (September 2014) ‘Water Conservation, Industrial Cooling Challenges, and Titanium' presented at TITANIUM 2014, Hilton Chicago, Chicago, IL USA

Large scale developments in commercial real-estate, power generation, and hydrocarbon processing place a heavy burden on local water resources and the environment. In many regions of the world, the use of fresh, potable, or desalinated water for industrial cooling is limited or severely restricted. Developers are forced to look at alternative sources of cooling water or other methods of heat rejection to balance competing energy, environmental, and water conservation goals. The use of available seawater or treated sewage effluent as a cooling media can be an effective water conservation strategy but also presents unique challenges in terms of equipment reliability and maintenance. This presentation will look at several examples of how the use of titanium in heat transfer equipment enables developers to plan for a wider range of cooling water conditions, and better serve the local community’s water and energy conservation needs.

Powder metal (PM) titanium technology offers a viable processing alternative to conventional manufacture of titanium parts from titanium mill products.  There has been significant recent increased global interest in advanced technologies such as additive manufacturing and new methods of producing titanium powder that have many hurdles to overcome. Dynamet’s mature processing approach for manufacture of high quality near-net shape titanium products is increasingly being qualified for use in demanding applications including aerospace.

The compatibility of titanium with graphite fibers in advanced composite aircraft structures has resulted in the increased use of titanium in aircraft.  Titanium is strategically replacing aluminum in aircraft structures because aluminum corrodes in contact with graphite in the presence of moisture.  The near net shape capability of powder metal (PM) titanium alloy preform shapes and reduced machining required offers users a significant cost advantage.  This need along with the maturity of the powder metal sinter and sinter + hot isostatic press (HIP) processes has prompted Boeing to qualify Dynamet’s PM Ti-6Al-4V alloy for commercial aircraft applications.  This presentation will provide an overview of the qualification process for PM Ti-6Al-4V, and the properties that can be achieved with As-sintered and with Sintered + HIPed PM Ti-6Al-4V produced by an elemental blend approach.  The shape making capability of the PM titanium process will also be illustrated.  Additionally a new ASTM specification for PM titanium alloys, including but not limited to Ti-6Al-4V alloy, has just recently issued.  It is anticipated that this will facilitate the adoption of PM titanium produced, by this manufacturing method and other powder consolidation methods, for application for military, medical and industrial components and general use applications.

In addition to the manufacture of conventional titanium alloy compositions, powder metal manufacturing is an enabling technology for developing and producing novel titanium alloy compositions and metal matrix composites. Examples of these non-conventional compositions, resulting material properties and current and future product applications for industrial and medical applications will be presented.


Baeszler,Ken  (October 2013)'RE-EVALUATING THE EDM PROCESS FOR TITANIUM MACHINING' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Until recently, many manufacturers of titanium components have considered Electrical Discharge Machining (EDM), either completely off limits, or to be used as a primary process coupled with a secondary operation. Many times, the secondary operation is solely in place to remove the parent material damage caused by the thermal process of EDM.  Recent improvements in electronics have led to the development of new clean EDM generators that substantially reduce the heat affected zone and micro-cracking caused by the thermal removal of material.  In addition to research completed at AgieCharmilles, independent studies are cited from the University of Birmingham that provides evidence supporting the re-evaluation of the EDM process, including:

•  Improved EDM technology processes

•  A review of EDM surface integrity results showing reduced heat affected zone and near zero recast layer and residual stresses.

•  Fatigue resistance tests comparing the EDM process with the milling process.

•  Alternative wire electrode materials (coated, pure steel) showing improvements in cutting speed and elimination of Zn and Cu contamination.

•  Ability to control the thickness of the oxide layer through manipulation of the generator spark characteristics.

Today’s clean EDM technology opens up new avenues of manufacturing for many titanium applications. Intricate parts can now be designed with the EDM process in mind, thus reducing tooling and material cost, improve deliveries and eliminate secondary operations.

The Commonwealth Science Industry Research Organization (CSIRO) is Australia’s national science agency, has an integrated supply chain oriented development program specifically focused on titanium.  Originally built off platforms for novel titanium metal production, the program has grown to include processing and manufacturing techniques including additive manufacturing and machining technologies.  CSIRO leveraged off of Australia’s mineral wealth of titanium bearing ore years ago and is this investment is beginning to pay off.  Soon Australia will join the exclusive club of titanium metal producers and has become an integral part of metallic additive manufacturing.  To that end, CSIRO has been deploying scientists in concert with industry partners, to develop a means to enhance these technologies.  This presentation will focus on advances and unique capability that CSIRO has developed around metal production and its current state as well as unique capabilities in additive manufacturing powder and machining.


Barrett,James  (October 2013)'APPLICATIONS FOR LIGHT WEIGHT MATERIALS IN MODERN MILITARY VEHICLES' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 The changing nature of the battlefield has generated a demand for lighter and stronger military equipment. The rapid timing of modern conflicts, for example, requires exceptionally fast deployment of military vehicles and artillery systems, bringing into consideration the load capabilities of available cargo fleets, fuel consumption, runway length in theater (given load weights), and rapid redeployment of equipment for maintenance and retrofit.

The asymmetric nature of the battlefield further requires quick and agile movement with minimum resource requirements. The terrain in these conflict areas is often unpredictable, and lighter equipment is ideal to reposition or withdraw in unimproved areas. Also, refueling stations and other resupply points are dependent on the security situation and are often managed by extra-military sources, making their availability unpredictable.

Cohen,Robert  (October 2013)'EMERGING MANUFACTURING PROCESS TECHNOLOGIES FOR TITANIUM AEROSPACE PARTS' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 In this presentation, Mr. Cohen discusses the technologies by which TECT machines components for aerospace applications and the advanced technologies under development. The most significant change in engines from the perspective of process technology is the transition to composite fan blades in engines. The trend of using composites in the engines of double-aisle airplanes has now moved to using more composites in the engines of single-aisle airplanes.

For TECT, this means the engine fan blades are changing from solid titanium to resin-based or metal matrix composite fan blades with titanium leading edges. Therefore, TECT is now focused on the technology for manufacturing titanium leading edges. 

When composite technology was first introduced, titanium suppliers were concerned that less titanium would be required on engines.  However, this has not been the case. With more complexity driven by the change to composite technology, the amount required versus complete blades turned out to be more than originally expected. In addition, as more metallic parts on the platform are replaced by composites, titanium is needed to serve as a bonding agent.

The input weights are different, but engines still use a fair amount of titanium, he says. And with all the new composite applications on the airframe, the amount of titanium used is pretty astronomical.

Dewhurst,Philip  (October 2013)'GLOBAL SUPPLY OF TITANIUM SPONGE' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Between 2003 and 2012 there were two periods of rapid growth in output of titanium sponge interrupted by a sharp fall in 2009, with the result that in 2012 sponge production reached 236kt, more than three times that in 2003.  This was principally a result of massive expansion in industrial quality capacity in China, combined with rising output in Japan and Russia particularly since 2009. 

The sharp increase in titanium sponge production between 2010 and 2012 was due to rising demand for both aerospace and industrial applications combined with a fear of a shortage of suitable titanium feedstock, particularly in 2012. As a consequence, sponge consumers built up considerable inventories, and a fall in production is expected in 2013.

In 2013, there are 23 companies worldwide with capacity to produce 333ktpy of titanium sponge: fourteen in China, three in the USA, two in Japan and Russia, and one each in Kazakhstan and Ukraine.  Rotor grade capacity, mainly in Japan, Russia, Kazakhstan and the USA, is estimated to be about 130ktpy.

The paper draws together historic titanium sponge output data by country and company showing recent trends in global output, and capacity developments in producing companies. It outlines the factors that have driven the titanium sponge market since the world economic slowdown in late 2008, and looks to future trends.  Corporate control of the titanium sponge market is summarized, and the impact of company projects on future supply is analysed in relation to forecast aircraft output to 2018.

The innovative ADMA non-Kroll process for manufacturing the hydrogenated titanium sponge and powder will be presented. ADMA has designed and installed a pilot scale manufacturing unit with annual capacity of 250,000 lbs of titanium hydride (TiH2) powders. It has been demonstrated that use of hydrogen reduces the powder manufacturing cycle to less than 24 hours. The ability to produce the titanium hydride powders with consistent chemical composition, characteristics and quality will be discussed.

It will be shown that the titanium hydride powders can be used in production of CP Titanium or Titanium Alloy components via the low cost Blended Elemental Powder Metallurgy (BEPM) approach. The atomic hydrogen reduces the impurities content in Titanium P/M products to AMS specification requirements and, subsequently, hydrogen is completely removed during sintering operation.

The ADMA patented processes (ADMATALTM) provide the best combination of mechanical properties, and the microstructures of titanium alloys are free of the defects, typically attributed to high interstitial content observed in titanium alloys produced from conventional magnesium reduced or sodium reduced titanium sponge fines. Extensive tests have been consistently demonstrating the properties that meet and surpass those obtained via conventional ingot metallurgy processes.

 Titanium alloys exist in several allotropic forms: alpha, beta and gamma.  The former is relatively easy to machine.  Alloys with a combination of alpha and beta phases (Ti 6Al-4V being the most common) are more difficult.  Fully beta alloys have become prominent over the last 10 years and are considered quite difficult to machine.  Gamma alloys (based on the Ti-Al intermetallic system) are attractive because of their impressive mechanical properties and because they are non-flammable.  These later alloys are very difficult to machine.

The machinability characteristics of the various alloys will be discussed.  Included will be a discussion of modern techniques such as the use of high pressure coolant for turning, peel milling, dynamic milling and trochoidal milling.  The impact these cutting techniques have on production cost, productivity and surface condition will be covered.

Kooman,Piet  (October 2013) 'HIGH STOCK REMOVAL WITH ABRASIVE BELTS' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
Over the last years, Timesavers supplied and developed machine equipment to grind Titanium sheets and plates. After severe R&D Timesavers introduces a new machine that changes the way metal parts are machined. The machine has been developed in cooperation with the Technical University of Delft, located in the Netherlands.

In engineering this new machine concept, particular attention was paid to its design and ergonomic features. The result is a high-tech machine with intuitive control, easy access to the abrasives, and simple and fast work piece loading/ unloading.

This completely new design of machine has the advantage that it can process larger parts, quicker and more accurately ( +/- 0,01 mm), and to a finer finish (Ra < 0,2 µm), than conventional grinding machines. At its heart is a reciprocating table that runs on precision bearings, as opposed to standard wide belt grinding machines which usually have a conveyor belt or a roller feed table

The Timesavers’ reciprocating grinding machines make use of the advances in coated abrasive belt technology. By using an endless belt the Timesavers machine is incredibly easy to retool. Because it is the roller, which remains on the machine, which is dynamically balanced, changing the consumable needs no special training nor does the consumable itself require balancing; with the dynamic forces controlled within the machine not on the consumable, far higher abrasive surface speeds can be employed: more grits per second translates into higher stock removal rates and finer finishes. Changing from a course belt for high stock removal to fine finishing is a matter of moments without having to use any tools.

The machine is fitted with a vacuum table that can hold a range of parts, small or large, thin or thick; it’s possible to routinely grind parts as thin as 0.18 mm with a clever adaptor plate. Another feature of the vacuum table is its ability to hold complex flat parts even if they have multiple holes, and still achieve a maximum holding vacuum. The vacuum table is integral to the machine

The powerful software in the human machine interface allows the operator to list parameters within a program. When running in manual mode, the operator has the choice of saving current settings as program steps; a simple to use ‘teach-in’ function.  To optimise machine use further, an operator can dictate grinding belt speeds, table traverse speeds, stock removal per pass or per cycle, the amount of cycles and the grinding belt direction.

An easy access coolant filter with a large recycle pump keeps the machine clean inside; the grinding cabin with a specially designed water curtain ensures all the grinding dust is flushed out preventing interference with the grinding process or disturbance of delicate finishes.

Timesavers has a well-equipped grinding laboratory, in which we can run samples for customers and use it for our own research.


Kreitman,Kevin L. (October 2013)'TITANIUM AND COMBUSTIBLE METAL SAFETY' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Metals in a combustible form including titanium, can present fire and explosion hazards.  Improper handling of these materials in fire incidents, place personnel and responders at great risk, these risks however can be minimized through proper pre-planning, engineering, housekeeping, and training. 

Preventive actions are important to minimizing potential fire and explosion hazards.  Knowledge of the risks associated with the metal and the form it is in along with proper housekeeping will greatly reduce risks and likelihood of an incident.

Should an incident occur however, how the incident is handled is critical to a safe outcome.   The proper handling of fires involving titanium and metals in a combustible form does not occur by happenstance.  One of the most important items is to ensure that pre-planning with emergency responders on the risks and hazards associated with titanium and other metals in a combustible form has taken place prior to the incident, to ensure proper actions are taken in the handling of the emergency which is critical to a safe outcome. 

Developing a close working relationship with the facility and working closely with facility personnel is a must to minimize risks for the facility and emergency responders.  Incidents involving a fire at a titanium or other facility involving metals in combustible form may very well present additional risks based on the form of the material involved, such as powders, dusts, molten metal, as well as the potential involvement of chemicals that may be associated with the processing of the metal.

It is essential that facility personnel and emergency responders develop a close working relationship and policies and procedures to ensure the safe handling of incident should they occur.  This presentation will provide a general overview of NFPA’s Combustible Metal Standard, the importance of housekeeping, and the proper handling of fires involving titanium and metals combustible form.

 The production of Ti 6Al-4V beta processed extrusions have grown in leaps and bounds over the past 10 years as extrusions have They replaced other wrought forms of titanium and aluminum in commercial aircraft and the industry looks for near net materials that are compatible with the construction.

Due to process constraints faced by many extruders almost all titanium shapes are processed in beta range. The resultant beta microstructure while quite acceptable for many structural components has intrinsically poorer fatigue properties as compared to what 6Al-4V will deliver when it has been alpha beta processed. Also 6Al-4V that has been beta processed will also not respond to the STA heat treatment that is used to strengthen the alloy.

Nu-Tech does not face such processing constraints and can extrude 6-4 in the alpha beta range.  The author will discuss Nu-Tech Precision Metal’s experience alpha beta extruding 6 Al-4V. He will also compare the hot working of 6-4 extrusions to other hot working methods and then present the exceptional longitudinal, transverse, and radial mechanical properties, and the texture found in extruded shapes, bars and hollows.

The development of alpha beta extrusions allows for such advantages as:  6-4 hollows that can be heavily cold worked, large near net alpha beta extrusions that can replace forged block and heavy plate, stronger (STA) 6Al-4V extruded hollows with better fatigue properties, and extruded bar and shapes that can be a cost effective substitute for rolled bars and closed die forgings when there are low volume requirements.  The author will also review the current level of acceptance within national standards and industry sectors.

Mandal,Sudipto  (October 2013)'TEXTURE CHANGES AND VARIANTS SELECTION DURING TRANSFORMATION OF BCC TO HCP PHASE IN TITANIUM ALLOYS' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Co-author: A.D. Rollett

Keywords: Titanium, texture, orientation relationship, misorientation, phase transformation

Titanium alloys are widely used in industries like aerospace, chemical, energy etc. due to their high strength-to-weight ratio and excellent mechanical and corrosion properties. Their mix of hexagonal and bcc phases at room temperature mean that the prediction of their anisotropic mechanical properties is challenging. However, at elevated temperatures these materials are single-phase bcc. During the transformation from BCC to HCP, the parent and product phases are frequently observed to obey Burgers orientation relationship. According to the Burgers OR, the close packed {011} plane of the bcc lattice is parallel to the close- packed (0001) plane of the hcp lattice and the <111> direction in the bcc lattice is parallel to the <11-20> direction in the hcp lattice.

In the present study, information about grain size, shape, misorientations and orientations for a beta-stabilized Ti alloy are extracted from experimental EBSD data and are used to create 3D microstructures using DREAM3D software. In order to study the texture changes and variants selection during the transformation, hcp grains are inserted into a single crystal of bcc and all the twelve variants are generated by imposing the Burgers OR. Misorientation statistics obtained from the simulation are then compared with experimental data.

Marks,Harold  (October 2013)'COIL TO BAR PEELING PROCESS FOR EFFICIENT VERTICALIZATION OF SMALL DIAMETER QUALITY PRODUCTS' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 PURPOSE:  Our paper introduces the advantages of production of peeled bars from hot rolled coils.  The new technology of coil to bar peeling allows to optimize the processing in the rolling mill increasing the output producing small diameters bars in coil not in straight length.  The proposed technology will also reduce the peeling processing cost due to several advantages like the minimization of the removed material and the handling procedures.

METHODOLOGY:  The peeling process from coil needs special solutions mainly on wire preparation.  Straight the coil in a proper way is a must in order to obtain a good quality on the final product in terms of tolerance and triangularity, to do this two straightening system are installed in line: the wire is pre-straightened by a H/V multi-roll straightener and after the wire pass through a horizontal and vertical cold rolling head able to remove all the memory form from the material compressing it and at the same time improve size tolerance reducing at minimum metal removal.

RESULTS:  This process gives important advantages on the peeled bar production:

-  Optimization of the hot rolling process with benefits on the rolling mill.

-  Reduction of the metal removal on the bar increasing the material yield.

-  Increase tool life.

-  Complete in-line process without any intermediate storage area.

-  Modular process that could be connected with non-destructive tests, chamfering, bundling…

-  High output of prime quality material

-  Fully automated line and smart lay-out solutions allow a single operator to manage the complete process.

 Highly alloyed Titanium alloys as Ti-1Al-8V-5Fe (Ti-185), Ti-5Al-5Mo-5V-3Cr (Ti-5553), Ti-10V-2Fe-3Cr (Ti-10-2-3), Titanium Aluminides and others processed from ingots require special melting approaches, repeated homogenizing heat treatment and hot working operations to minimize segregations. With low cost Blended Elemental Powder Metallurgy (BEPM) manufacturing approach, the products are inherently homogeneous and do not require any special processing to minimize segregations.  This presentation will discuss a unique and low cost ADMATAL™ process for manufacturing the highly alloyed Titanium materials from Hydrogenated Titanium powders. It would be demonstrated that Low-cost Powder Metallurgy (PM) process can be successfully used for manufacturing the various high-alloy titanium alloys Ti-1Al-8V-5Fe (Ti-185), Ti-5Al-5Mo-5V-3Cr (Ti-5553), Ti-10V-2Fe-3Cr (Ti-10-2-3). It would be shown that the microstructures and phase composition of these alloys can be widely modified using the different sintering cycles and heat treatments. This allows improving the combination of their mechanical properties that are meeting or exceeding the properties of the identical alloys produced by traditional ingot metallurgy processes.


McCoy,David  (October 2013)'TITANIUM VALUE-CHAIN: SAND TO MELTED PRODUCTS.' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
  Titanium minerals have seen an unprecedented surge in cost for sponge producers of the last two years. First it was rutile, which jumped 340% in price of a weighted average traded basis (higher in the spot market) between 2010 and 2012. More recently, the price for other high-titanium content feedstocks used to make sponge have become more expensive as legacy contracts progressively expired. The changes in manufacturing costs to produce sponge have change so much in recent years that sponge companies started to explore alternative feedstock sources and mixes, while at the same time trying to ensure no net impact on sponge quality.

Titanium sponge producers are expected to account for around 6% of 2013 mined feedstock units. No longer is rutile, nature’s highest quality TiO2 mineral, an insignificant cost when making a tonne of sponge.  So does this mean that producers of sponge will need to look at lower quality titanium feedstocks? Does the importance of scrap rise in the value chain?

The solution may be a mixture of new and old suppliers, with some rebalancing between the sources of minerals and alternative titanium units.

There has also been rationalisation in the suppliers for high-titanium content feedstocks in recent years. Two of the world’s largest TiO2 pigment producers have back-integrated into the titanium feedstock market. These producers are expected to progressively demand more of their own high-grade minerals be internally consumed in the chloride process to manufacture TiO2 pigment, leaving less for the external sponge market.

All of this is driving up the cost of sponge manufacture. One Japanese producer has publicly postulated that relocation of operations to other lower-cost countries may be considered. The use of scrap in melted products has increased as the cost-gap between sponge and scrap widened.

In China there has been a rapid expansion of titanium slag production capacity, primarily using small, batch process technology which currently operates at very low efficiency. Similar technology is being rolled out in Vietnam and India, as governments require value-add processes to be employed rather than basic raw mineral exploitation. There are approved projects in Vietnam to expand further into the sponge sector, while in India a small scale commercial plant was commissioned in 2012.

In this paper, TZMI will present a holistic review and independent forecast of the global titanium mineral market, focusing on its impact on titanium sponge producers. TZMI will also place the titanium mineral demand for sponge manufacture in context with the growing global supply base for titanium sponge and its demand for use in melted products.

Mertens ,Tobias  (October 2013)'INVESTIGATION OF SELF-ORGANIZED Ti02 LAYER AS PRE-TREATMENT FOR STRUCTURAL BONDING OF TITANIUM' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 In the aerospace industry new design concepts offering weight savings are high in demand. In the recent generation of aircraft (e. g. Airbus 350 XWB, Boeing 787), composite materials have shown new perspectives in terms of structural efficiency and performance. Due to the increasing amount of composite materials used in the aircraft structure, new corrosion concepts have to be developed. In order to avoid galvanic corrosion, more titanium has to be used in aerospace (14 wt.-% in Airbus 350 XWB). To increase the efficiency and performance of the aircraft the connection between composite materials and titanium should be realized by adhesive bonding. However, it is well-known in aerospace industry that titanium materials exhibit critical issues in regard to long-term stable adhesion. Reflecting this, the surface treatment is the most important step to ensure durable bonds.

Within this work, a TiO2-nanotube layer is formed by anodisation. This anodisation process is used as a pre-treatment for structural bonding of the titanium alloy Ti6Al4V. For reference, an alkaline etching process (Turco 5578) and a second anodising procedure in an alkaline anodising electrolyte (NaTESi process) are employed to evaluate the TiO2-nanotube structure.

Using the TiO2-nanotube process, the surface area could be enlarged by a factor of 20, compared to the initial surface after alkaline etching. The mechanical tests (floating roller peel test, wedge test) show that the area enlargement due to the anodising processes enhances the bonding durability in hot/wet conditions. The results obtained, confirm the correlation between the morphology and the bond strength. The improved adhesion properties after the anodising pre-treatments can be related to the contributions from the mechanical interlocking of the adhesive in porous oxide layers and the chemical and physical interactions between the hydroxylated surface and the epoxy film adhesive.

Using the TiO2-nanotube anodising at 5 V and 15 V, respectively, a high resistance against crack growth can be achieved. In comparison to the other treatments (NaTESi process, alkaline etching) the TiO2-nanotube anodising leads to the lowest crack growth under hydrothermal conditions.  The investigations show that in principle the TiO2-nanotubes can be used to achieve a long-term stable adhesion on Ti6Al4V even at combined mechanical and hydrothermal loads.

Mitchell,Gene  (October 2013)'TITANIUM IN SHIPBUILDING' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Titanium and its alloys offer many benefits for naval ship applications due to their well known properties including high corrosion and erosion resistance, high strength to weight ratio and in the case of one particular TIMET alloy, very high fracture toughness and stress corrosion resistance of base materials and welds. However excessively high initial cost, including welding fabrication cost, continues to present a strong impediment to wider scale usage of titanium for achieving improved system performance and life cycle cost savings. Mr Mitchell will present a brief overview of the following aspects of titanium usage in naval ship applications:

• Examples of current applications of CP and alloy titanium

• A development program for replacing a nickel based alloy with titanium alloys

• Cost, service and fabrication related factors impeding the wider use of titanium.

• An example, involving titanium, illustrating the need for better overarching coordination of research and development work so as to significantly improve computational methods for engineering characterization of material performance.


Okamoto,Akio  (October 2013)'KOBE STEEL SUPPLIES HIGH HEAT TRANSFER TI SHEET FOR USE IN OTEC DEMONSTRATION PROJECT' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Kobe Steel, Ltd. has supplied a high heat transfer titanium sheet called HEET™ for use in the heat exchangers of an ocean thermal energy conversion (OTEC) power system in a demonstration project in


Kumejima, Okinawa Prefecture. It is the first time that HEET™ has been applied in an OTEC power system.

OTEC power generation utilizes the temperature difference between deep seawater and surface water. Warm surface seawater is pumped through a heat exchanger where a low-boiling-point fluid, such as ammonia, is vaporized. The resulting steam drives a turbine to generate electricity. Cold deep seawater goes through a second heat exchanger to condense the vapor back to liquid. The high heat transfer titanium sheet enhances the heat transfer performance by more than 20 percent. This HEET™ application is hoped to make large advances in lowering the power generation cost to verify the practical use of OTEC power generation, which is attracting attention as a renewable source.

 Authors:  James Paramore, Pei Sun, Z. Zak Fang, Mark Koopman, University of Utah

Keywords: hydride, hydrogen, low-cost, metallurgy, PM, powder, sintering, titanium

Hydrogen sintering and phase transformation (HSPT) is a new, low-cost, powder metallurgical process to produce titanium alloys with mechanicals properties that exceed ASTM standards for wrought titanium alloys.  Powder metallurgy (PM) has long been sought after as a means to reduce the cost of titanium products, as the majority of cost associated with titanium stems from the complicated and energy intensive wrought processing methods that are currently employed in industry.  However, PM has fallen short as a viable means to produce titanium for critical applications due to poor densification and the undesirable microstructures that result from traditional PM processes.  HSPT has several unique characteristics that set it apart from other PM processes.  During HSPT, compacts of TiHx powder are sintered under dynamically controlled partial pressures of H2 and subsequently dehydrogenated.  The presence of comparatively weak Ti-H bonds during sintering increases diffusion rates and, therefore, significantly increases densification kinetics.  This means full densification is achieved at lower temperatures and shorter times than those required for traditional titanium sintering.  Additionally, the Ti-H system undergoes a eutectoid transformation during cooling.  The decomposition of primary β grains during the eutectoid reaction results in significant microstructural refinement.  This phenomenon gives HSPT unprecedented control over the microstructure and mechanical properties of the alloy.  Therefore, by controlling the partial pressure of H2 throughout the thermal cycle, fully dense titanium alloys with engineered microstructures may be produced in the as-sintered state without the need for post-processing.  Because of this, HSPT shows great promise as a low-cost alternative to wrought processing for the production of titanium alloys with application-tailored mechanical properties.

 The merging of Exxaro’s mineral sands assets in South Africa, the Tiwest Joint Venture minerals sands/titanium dioxide operations in Western Australia and Tronox’s titanium dioxide pigment production facilities in the United States and Europe has seen Tronox become a significant, fully integrated titanium dioxide company with direct control over its entire supply chain from pit to pigment.

As a large producer and consumer, Tronox is active on both sides of the supply and demand environment for titanium feedstock. In this paper, Tronox will present commentary on the outlook for titanium feedstock supply based on its involvement in mineral sands production, and on feedstock demand both as a titanium dioxide pigment producer and a continuing participant in the marketing of feedstock into pigment and non-pigment applications externally. The latter includes welding consumables and titanium sponge markets.


Qin,Guihong  (October 2013)'RESEARCH OF HOT TANDEM ROLLING PROCESS OF TC6 TITANIUM ALLOY BARS' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 The test on effect of three kinds of tandem rolling process on microstructure and property of TC6 titanium alloy bars was conducted in this paper. The result shows that the microstructure and property of the bars produced by process one are able to meet the requirement of the specification, but the microstructure is not uniform, the content of primary αphase in the center of the bars is much more than than that of the edge. the bars’ which was produced by process two room temperature and elevated temperature tensile-strength can not meet the requirement of the specification. After analysing the reasons of the failure of the above two kinds of processes. However, Both of the microstructure and the mechanical property of the bars produced by process three are able to meet the requirement of the specification produced by process three.

 Ti- 6Al-4V is the most widespread titanium alloy and comprises 60 percent of the total titanium production. Titanium alloys microstructure is the most widely varied and results in the widest range of properties. Ti 6Al-4V is used in numerous applications in annealed condition with tensile strength of about 900MPa. STA condition gives rise to most pronounced strength, hence further advantage of specific strength in aerospace applications. The full hardenability of the alloy is limited to about 25mm thickness and achieving STA properties in a component becomes most difficult task. The paper brings out the various experimental and production trials carried out to achieve the full hardenability in the alloy component. It is observed that not only the quench delay, finer control of iron, oxygen and martensitic lath size contribute to the enhanced mechanical properties of the alloy.

 Authors: Hansjörg Rau, Jürgen Kiese, Jury Kazakov, Klaus-Peter Wagner

Outokumpu VDM, D-45143 Essen, Germany

Hearth melting of titanium and its alloys become more and more important. The original reason was to eliminate any inclusions from titanium alloys particularly used in critical rotating parts. Nowadays, environmental and economic aspects are becoming increasingly important. As the main reason may be mentioned here, protecting the world's resources by using the high volume of the existing titanium scrap.

Electron Beam Cold Hearth Remelting of titanium is a well-established melting technique at Outokumpu VDM. The EB furnace is located at the production site in Essen and its maximum capacity is 5,000 metric tons/year. Typical products are rectangular slabs and round ingots. The products reach lengths up to 5.5 meters weighing up to 16 metric tons. The produced alloys to this date are cp grades 1 and 2 as well as Ti-6Al-4V and its ELI grade. The round ingots especially made of Ti-6Al-4V can be taken for an additional melting in the vacuum arc remelting (VAR) furnace (EB+VAR). At the production site of Outokumpu VDM there are three VARs available.

Since 2008 the total amount of melted Ti-6Al-4V at Outokumpu VDM is more than 700 metric tons and the demand grows rapidly.

The melting of the Ti-6Al-4V alloy in an EB furnace is a challenge. The most important issue is to control the Aluminum content because of its pronounced evaporation during the melting process. It has been shown that it is absolutely necessary to obtain a stable process with a constant melting rate. Only in this case it is possible to realize homogenous products during a melting campaign with several ingots. Examples will be given that a homogeneous distribution of alloying elements is present both on the ingot length, as well as on the cross-section. Likewise it is shown that this is in a good relation with the conventional sampling by drilling. Moreover it is also demonstrated that this is in a good agreement within the semi-finished product.

The results of an experiment with seeded particles of hard metal show impressively that hearth melting is an appropriate measure to eliminate inclusions. It was observed that both a separation and dissolution of the particles took place.


Rose,David L. (October 2013)'CLOSING THE LOOP' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 As any market or industry matures, the dynamic of competitions’ quest to add differentiable value to their customers becomes harder and harder.  Whether it be consolidations on the ‘supply’ side or the ‘buy’ side, fluctuations in commodity prices, or other obstacles; the challenges grow every day. 

Within the Aero, Energy, and other super alloy revert markets, ‘closing the loop,’ the process of recovering one’s own revert stream at all points of the supply chain, is becoming the new norm.  As melters become more and more dependent on revert as a high percentage of their charge volume;  finding quality revert of known origin, at competitive prices, has dominated the thinking of the supply chain teams within these organizations.  Establishing a revert supply partner with dependable and known sources has become key to their success.

‘Closing the loop’ is not rocket science, it is just common sense.  By recovering more of their own revert stream, they not only create a supply stream, they also better control the quality of the revert they buy and use.  A more comprehensive review of this concept will be shared during the PCC Revert Group presentation.

 This presentation will briefly summarize the points made by the other session panelists and attempt to tie together the common threads of the feedstock market, the sponge market, the master alloys market and the scrap market. Included will be commentary regarding possible future developments in each of these markets. There are significant interdependencies between feedstock, sponge, master alloys and scrap. This presentation will focus on these interdependencies in an attempt to provide insight to the audience as to what developments should be monitored in order to best estimate the future of these highly volatile elements of the titanium mill products supply chain.

Building upon this theme, the presentation will also discuss information available related to these materials in the public domain to help monitor market developments. Information regarding our industry is both more and less accessible than it has ever been. With consolidations occurring in recent years, the amount of market information being released into the public domain by titanium producers and consumers is in many cases more limited than it has been in the recent past. However, government statistics and international trade information is more easily accessible than it has ever been. This necessitates that marketers and analysts turn to different sources for their insights than they may have leaned on in the past. This presentation will explore how one may go about approaching this change to market statistics to best stay ahead of the curve.

Stansbury,Trevor  (October 2013)'EXTENDED ENTERPRISE COLLABORATION' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 Over the last 20 years (partially as a consequence of outsourcing) most Original Equipment Manufacturers (OEMs) have lost visibility into the titanium raw materials that go into their parts and therefore exercised little or no control over where those raw materials are purchased, what is paid for them and how they are supplied. Consequently, titanium demand information flows slowly and sequentially, if at all, to those stake holders that have the greatest need for it - the raw material distributors and mills.  Ironically, most OEMs have invested vast resources on leaning-out the value-added component of finished part cost, while ignoring the waste and inefficiency on the raw material side of the total product cost equation.  Mr. Stansbury, an expert on extended enterprise collaboration and will share  how some of the world's largest OEM's and their sub-tier suppliers are collaborating to address those challenges by leveraging aggregate, consolidated titanium demand to obtain the very best pricing and service levels.

Walker, Scott,Trimmer, Andrew (October 2013)'THE BLUE ARC MACHINING PROCESS ' Paper Presented on Titanium USA 2013 Conference Proceedings. Titanium USA 2013, Caesars Palace, Las Vegas, Nevada, USA
 
 What is Blue Arc™? What are its benefits in a production environment? What are its applications in titanium? Who is developing it? When will it be available to manufacturers? All of these questions and more will be answered -- specifically how the technology relates to titanium aerospace structures, jet engine components, and power generation parts.

Chemical Engineer Mr. Andrew Trimmer, PhD at GE Research will discuss this exciting machining process and Mr. Scott Walker, President of Mitsui Seiki USA will relay valuable information about the machine tool requirement to apply the Blue Arc™ methodology successfully and efficiently.

Blue Arc™ is a High Speed Electro Erosion (HSEE) process that was developed to rough cut high strength aerospace alloys.  Fundamentally, BlueArc™ is a controlled thermal removal process driven by an electrical potential between a tool electrode and a workpiece. Thermal events are more intense and widespread than conventional EDM processes and are controlled by the applied potential and current, the electrolyte, and the distance between the tool electrode and workpiece.  Each thermal event erodes some of the workpiece resulting in bulk material removal.  Under most conditions the contact forces between the electrode and the workpiece surfaces are negligible enabling the use of slender electrodes or light duty machines.  End milling, peripheral machining, and shaped electrode profile machining have been studied.  In this seminar, machining results will be shared for nickel based superalloy and titanium alloy rough machining.  In each case material removal rates 2-3 times the conventional analog for similar size tooling was achieved.  BlueArc™ is a versatile rough machining process that can achieve high material removal rates and significant tooling and machine investment cost savings.

Titanium is used extensively in military applications because of titanium’s superior mechanical properties, corrosion resistance, ease of fabrication, and low density. These superior characteristics make titanium the material of choice for critical components in the military systems and platforms used to support the warfighter. This presentation discusses the current outlook for titanium applications in military aircraft, land, and sea vehicles that will impact future titanium demand.

 

 

Buch, James M. (October 2012) "Jet Engines.” TITANIUM 2012, Hilton Atlanta, Atlanta

Titanium volume into the engine market over the next 5-7 years will be driven by commercial high by-pass twin aisle engines, competition for fuel efficiency in the new and re-engined single aisle and regional jet segments, emerging and legacy military programs, and the burgeoning aftermarket. This presentation will look at these drivers as well as the impact of certain technological innovations in order to draw conclusions about the growth of titanium in this key segment through the rest of the decade.

 

Hickton, Dawne S. (October 2012) "Commercial Aerostructure Update.” TITANIUM 2012, Hilton Atlanta, Atlanta

The commercial aerospace industry, including its titanium aerostructure suppliers, faces a more competitive, global market than even a few years ago. New single-aisle competition progress from producers in Canada, Russia, and China, prompted both Airbus and Boeing to accelerate launches of their single-aisle jets and re-evaluate their supply chains in today’s post-duopoly commercial environment. Record backlogs for these more efficient single-aisles and twin-aisles have exploded, placing a premium on supply chain execution and capacity. Manufacturing locations are also shifting to make producers more globally competitive: Witness Airbus’ recent announcement to build its first U.S. assembly plant in Mobile, Alabama and its new assembly plant in Tianjin, China. Are titanium suppliers prepared to support these projected record production levels? What titanium aerostructure capabilities are critical to winning in today’s market? Are the projected delivery levels real relative to likely production? Can all these planes get financed? How might the European economic crisis and fragile U.S. recovery impact demand projections? Ms. Hickton will provide insight and analysis into the key drivers in titanium demand since her last commercial aerospace update in 2010, and also put this recent activity into perspective relative to other industry cycles. She will also inform the audience on the current state of the commercial aerospace aerostructure segment and the anticipated demand for aerostructure titanium in the future.

Crist, Ernie. (October 2012) "Development of RTI Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo Production-Scale Fine Grain Size Sheets for Low-Temperature Superplastic Forming Applications.” TITANIUM 2012, Hilton Atlanta, Atlanta

Ti-6Al-4V (Ti-64) and Ti-6Al-2Sn-4Zr-2Mo (Ti-6242) alloy sheets are widely used in monolithic sheet metal aerospace parts fabricated via superplastic forming (SPF), often in combination with diffusion bonding (DB). Conventional Ti-64 sheet is superplastic at temperatures above 1625oF (885oC), at which rapid tool deterioration occurs. Deep alpha case forms that requires removal by expensive and non-environmentally friendly chemical milling. Therefore, reducing SPF temperatures and cycle times are desired for the fabrication of parts via SPF/DB. In recent years, significant effort has been devoted to developing Ti-64 sheet that is superplastic at temperatures in the range 1450-1500oF (788–816oC). Aero-engine components currently manufactured from Ti-64 sheet are being converted to Ti-6242 to meet the demands of increased elevated temperature requirements. Consequently, OEMs and Tier 1 suppliers have expressed an interest in Ti-6242 sheet exhibiting "low-temperature” SPF behavior at or below 1550oF (843oC). As with Ti-64, lowering the SPF temperature will improve die life and eliminate the need for chemical milling. This presentation will provide an overview of fine grain size sheet manufacturing developments at RTI for low temperature SPF applications.

 

 

 

Saraf, Vikas. (October 2012) "Artificial Neural Networks to Predict Tensile Properties in Titanium Forgings.” TITANIUM 2012, Hilton Atlanta, Atlanta

Integrated Computational Materials Engineering (ICME) is being highlighted in the wide array of industries as a need to meet the demand of rapid process design and enhanced component capabilities. At the same time, the development and adaptation of predictive thermal, mechanical and microstructural models is becoming a norm in the aerospace supply chain. Many of such models are developed as deterministic in approach. Physics based models will have their place and requirement to understand the material behavior from the fundamentals to the application. But such models require wide amount of resources to develop and validate consistently. Fast acting model based on the Artificial Neural Network connecting known inputs with known outputs with a known degree of error is an approach that can be developed and adapted, relatively, faster to influence design and manufacturing decisions. In this presentation, the results of the neural network model developed to predict the mechanical tensile properties of the forged aerospace components of Ti64 material will be discussed. Various microstructural characteristics of Ti 6-4 such as primary and secondary alpha sizes and chemistry are included as inputs. A unique feature of Ti6-4 anisotropic behavior, crystallographic texture, is also incorporated as a modeling input. These inputs are trained using a neural network algorithm to predict the tensile mechanical properties. Microstructural inputs for the neural network model are generated using various validated computational models such as phase field, crystal plasticity, thermodynamic and variant selection. These models, ultimately, will help the designers to optimize the manufacturing process and yielding the desired properties for forged Ti64 components.

Tallman, Cory. (October 2012) "Thermal Assisted Machining.” TITANIUM 2012, Hilton Atlanta, Atlanta

Machining of Titanium is difficult because of its poor thermal conductivity and high toughness. Lockheed Martin Aeronautics (LM Aero) demonstrated and evaluated enhancements achieved by using a laser in front of the cutting path to soften the material. Results were such that a commercialization project called Thermal Assisted Machining (TAM) is now underway. LM Aero is involved in this commercialization effort as a part of a Commonwealth Scientific and Industrial Research Organization (CSIRO) managed industry team. The main objective of the project is to integrate a state-of-the-art laser system with a modern CNC five-axis milling machine to result in a production capable TAM cell to reduce roughing machining times by up to 80% and increase tool life by up to 3X. The technology will be licensed to an equipment manufacturer to make the technology broadly available to F-35 suppliers and others machining titanium.
The 4 kW fiber delivery diode laser has a built-in, real-time, closed-loop temperature control system. The appropriate energy distribution and beam shape will be determined and integrated appropriately with the tool path programming to optimize the process.

 

 

 

Young, Charles S. (October 2012) "Titanium is NOT Too Expensive.” TITANIUM 2012, Hilton Atlanta, Atlanta

When a Titanium Industry representative talks with maintenance and process engineers, purchasing agents or management in any of our chemical processing "end use” industries, there is always one or two individuals in the audience who consistently raise the concern that "Titanium is too expensive to use in this application.” Alternative materials, such as nickel alloys, duplex stainless steels, copper-nickel alloys, etc. are seen by these individuals as being less expensive and more cost effective. While this may have been true a number of years ago, when pricing of materials was entirely different, it is definitely not true today. In this presentation, I will show that, when using a "Normalized” price approach to compare materials, titanium is very cost competitive and can even offer a cost advantage to materials with less or similar corrosion resistance. This approach can be effectively used to overcome cost-based objections and increase the potential for titanium in the chemical processing industry.

 

 

 

Ugarenko, Charles. (October 2012) "Titanium Internals in Refractory Lined Pressure Oxidation Autoclaves.” TITANIUM 2012, Hilton Atlanta, Atlanta

This paper provides an overview of the design considerations, manufacturing techniques, quality assurance and installation of titanium compartment walls, baffles and anchor brackets for use in metallurgical autoclaves. Hatch pioneered the use of titanium autoclave internals in 1996 at Barrick Gold Corporation’s Goldstrike facility in replacement of hydraulically inefficient, maintenance intensive and voluminous refractory brick internal structures. Titanium is a proven material of choice for autoclave internals due to its service longevity in the high temperature, acidic and abrasive environment found in metallurgical autoclaves. Employing computational fluid dynamics and stress analysis, and fabrication techniques developed by W.E. Smith Engineering, Hatch has successfully implemented titanium compartment walls and baffles on a number of autoclave projects, including four of the world’s largest refractory lined pressure oxidation autoclaves at the Pueblo Viejo Project in the Dominican Republic.

 

 

 

Baldauff, Regis. (October 2012) "Titanium and Copper Nickel Properties and Characteristics-Titanium's Comparative Advantage.” TITANIUM 2012, Hilton Atlanta, Atlanta

Copper Nickel Pipe and Fittings have been specified for multiple Naval, process plants and offshore petroleum production applications for many years and are well established as the metal of choice in the Marine Industry. With that said, a closer comparative analysis between Titanium and Copper Nickel reveals a much different story. This presentation will provide an overview comparison between the two metals in a seawater environment. We will present data that revels how titanium offers a competitive advantage over Copper Nickel in weight savings, life cycle cost, maintenance costs, corrosion resistance and many other areas. Therefore, based on these comparative results we will show why "Initial or First Price” should not be the only evaluation mechanism used for determining which is the best metal of choice. Comparisons between these metals properties include Mechanical, Physical, Corrosion resistance, Erosion, Volume & density. Advantages of Titanium and its Applications in the Marine industry and for general seawater service are also presented.

 

 

 

Ferreira, Neidenei Gomes. (October 2012) "Production and Characterization of Boron Doped Diamond Electrodes Grown on Titanium, Applied to Textile Dye Degradation.” TITANIUM 2012, Hilton Atlanta, Atlanta

Recent advances in the water treatment process to industrial effluents led to the development of methods denominated Advanced Oxidation Processes (AOP). These processes can be defined as an oxidation method based on intermediated oxidant species or on hydroxyl radical formation highly reactive and as result the pollutant destruction. In parallel, advances in material science led to a large spectrum of materials for application in AOPs, where the electrochemical mineralization of organic pollutants is a relatively new technology for wastewater treatment without the chemical agent presence. In this context, the aim of this work was to develop diamond electrodes at different doping levels, and at different deposition times, grown on titanium substrates.

 

 

 

Truong, Vi Khanh. (October 2012) "Investigation of Bacterial Attachment Patterns on Micro-and Nano- Restricted Surface Topographies.” TITANIUM 2012, Hilton Atlanta, Atlanta

The use of metallic implants is increasing and diversifying; as is research into the use of titanium that has undergone bioactive surface modification to increase biocompatibility and eliminate bacterial biofilm formation. Biofilm formation by human pathogenic bacteria on medical implants can be problematic, most often leading to failure of the device and requiring its surgical removal from the patient. Biofilms can be associated with systemic infection, loss of limb or organ function, amputation or death. Therefore, it is critical to identify ways by which implant surfaces can be improved so that they can modulate the degree of bacterial attachment that takes place on their surfaces. In this study, the modification of titanium surfaces was achieved using two different approaches, namely the alteration of the surface architecture of the bulk titanium, and by coating substrate surfaces with thin films of titanium. For bulk titanium materials, equal channel angular pressing (ECAP) and femtosecond laser ablation were employed to alter the surface micro- and nanoscopic topographic parameters. A magnetron physical vapor deposition system was employed to fabricate titanium thin films containing particular sub-nanometric surface features. Radio-frequency plasma enhanced chemical vapor deposition (RF PECVD) was also investigated as a method by which titanium surfaces could be improved by coating the titanium surface with thin films of terpinen-4-ol, a constituent of tea-tree oil that has been shown to be anti-microbial. An optimized experimental procedure allowed the application of RF PECVD of terpinen-4-ol such that the resulting film retained the chemical integrity and functional properties of the original terpinen-4-ol.

 

 

 

 

Jewell, Daniel A. (October 2012) "Titanium Metal Production via Oxycarbide Electrorefining.” TITANIUM 2012, Hilton Atlanta, Atlanta

The growing needs of an ever developing world have led to an unprecedented demand for high-performance materials. To address this issue research has mainly focused on the invention of new materials which offer novel structures or compositions, e.g. CNTs and high- performance alloys. Whilst these can offer unparalleled properties in some areas, significant research and development is required before they can be employed widely, cheaply, and in useful quantities. There are occasions, however, when existing materials are available in significant quantities and have established industry, but the cost of extraction limits their wider use; titanium is such an example. Since the publication of the FFC-Cambridge Process[1] in 2000, an intensive worldwide research program was undertaken to develop novel titanium extraction techniques. A decade on, limited success has been achieved and the Kroll Process remains undefeated. A recent contender has begun to show promise as an alternative route to cheap, large-scale titanium production and is currently under investigation at the University of Cambridge. This method, called the Chinuka Process, is a novel electro-refining method[2-4] which uses a titanium oxycarbide anode to produce a purified titanium deposit on the cathode. A particular advantage is the ability to refine lower grade ores that are prohibitively impure for other titanium extraction processes.
