Titanium in the Military: What About Tomorrow?

Dawne S. Hickton

Vice Chairman, President and CEO

RTI International Metals, Inc.

 

Abstract:

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.

An Analysis of the Mechanical Properties and Microstructure Resulting from Cold Sprayed Ti-6Al-4V

Aaron Birt

Research Assistant

WPI


Abstract:

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.

Safe Handling of Combustible Metals


NFPA 484 Overview

Kevin L. Kreitman

Fire Chief

Redding California


Abstract: 

The 2015 edition of NFPA 484 Standard for Combustible Metal, has been released and supersedes all previous editions.  A number of changes are taking place within NFPA dust standards, in part based on comments from the Chemical Safety Board.  These include NFPA’s creation of a Technical Correlating Committee which now oversees all of NFPA’s dust standards and the current development of a new standard covering Combustible Dusts (NFPA 652) which is under development.

 

NFPA 484 was created in 2002 by incorporating the requirements of six individual combustible metal standards, including NFPA 481 Standard for Titanium, into a single document.  The six individual standards became chapters in the new standard.  A number of improvements have occurred over the last twelve years to consolidate requirements which are applicable to all metals in a combustible form along with new chapters to address emerging issues such as metal recycling facilities.  The goal of these updates has been to improve the safety of facilities handling metal(s) in a combustible form.

 

Why is NFPA 484 important to titanium industries?  The Chemical Safety Board and OSHA have both referenced NFPA Standards in investigations of incidents involving Combustible Metals.  Even though OSHA has not adopted a comprehensive dust standard, they have a National Dust Emphasis Program which references NFPA 484.  Additionally, OSHA has a resource page called Combustible Dust an Explosion Hazard, which includes Consensus Standards that lists NFPA 484 with the following statement:

 

Consensus Standards and the General Duty Clause

The General Duty Clause, Section 5(a)(1) of the OSHA Act, can be used to cite employers that fail to keep a workplace free of hazards, but only where there is no OSHA standard that applies to the particular hazard involved. In evaluating such situations, the hazard must be recognized (by industry or the employer), must have caused or be likely to cause death or serious physical harm, and a feasible means to correct the hazard must be available. Consensus standards may be used to provide a feasible means of abatement and establish employer and industry knowledge.

 

Section 5(a)(1) is not:

·         used to enforce "should" standards.

·         used to require abatement methods not required by a specific standard.

·         normally used to cover categories of hazards exempted by an OSHA standard.

 

The Chemical Safety Board in their recent investigations of incidents involving metals in a combustible form has also reiterated the following:

2006-1-H-1:  Issue a standard designed to prevent combustible dust fires and explosions

in general industry. Base the standard on current National Fire Protection Association (NFPA) dust explosion standards (including NFPA 654 and NFPA 484)…

 

The 2015 NFPA 484 Standard for Combustible Metals, contains a significant reorganization and new material consolidating and creating new chapters which are applicable to all metals in a combustible form.  A number of the items in these new chapters are applicable to new and existing facilities.  A review of these changes along with an overview of OSHA’s Combustible Dust information and Chemical Safety Board recommendations related to Titanium will be discussed.

Powder Metallurgy Session


Near Net Shape: From Dream To Reality (different than what is on t)

Alain Honnart

Managing Director

Metalvalue Ltd.


Abstract:

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.

Fundamentals of Low Cost Titanium Hydride Powder Metallurgy

Dr. Orest Ivasishin

Institute for Metal Physics


Abstract:

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.

 


Manufacturing of Titanium Components for Critical Applications from Hydrogenated Titanium Powder

Dr. Vladimir Duz

Director of Research & Development

Abstract:

Innovative powder metallurgy processes for manufacturing the titanium components for critical applications from hydrogenated titanium powder will be presented. The manufacturing of titanium alloy components by low cost blended elemental approach that includes various room temperature consolidation techniques (die-pressing, direct powder rolling, and cold iso-static pressing) followed by sintering and high temperature post processing (forging, rolling, extrusion, ring rolling) will be discussed. It will be demonstrated that the low cost ADMA patented powder metallurgy processes (ADMATALTM) provide the best combination of mechanical properties that meet or exceed the properties obtained on the identical titanium alloys by conventional ingot metallurgy processes. Phase and structural transformations occurring upon these innovative processing and resulting microstructures/properties relationships will be also discussed.

Water Conservation, Industrial Cooling Challenges, and Titanium.

Craig Thomas

VP Marketing & Sales

G & L Manufacturing


Abstract:

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 communities water and energy conservation needs.

Mitja Mahnič

Senior Project Manager

Akrapovič


Abstract:

Everyday demands for improving fuel efficiency, reducing exhaust emissions and improve vehicle performance, force designers to reduce vehicle weight. Exhaust system applications, including mufflers and exhaust pipes are one of the main targets. Since titanium was introduced as an alternative material for exhaust system, Akrapovič Company has been constantly looking for new technologies that help us speed up the production process and reduce the manufacturing costs and is therefore more attractive to original-equipment manufacturers (OEM). Parallel with our standard design process, several new approaches are introduced to additional reduce the exhaust weight. This paper presents our new challenges in the development of the lightweight exhaust system: introducing thin wall structures, designing special elements (flexible joints) made of new titanium alloys and finally joining different materials to optimal withstanding applied loads.

 

     

Photocatalytic Activity of Anodized Titanium Sheets under Ultra-violet and Visible Light Irradiation

Michio Kaneko

Steel Research Laboratories

Nippon Steel and Sumitomo Metal Corporation


Abstract:

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.

**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.

 

           

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

Peyman Samimi

Center for Advanced Non-Ferrous Structural Alloys

University of North Texas, Denton, TX

 

Abstract:

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.

Cleanliness Related to Post-Fabrication Processing of Additive Layer Manufactured Porous Surface

Julius Bonini, PE

Senior Metallurgical Engineer

Lucideon M+P

 

Abstract:

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. 

 

      

Titanium 3D Printed Treatment of Sleep Apnoea

John E. Barnes

Director, Titanium Technologies - CSIRO

Adjunct Professor, Royal Melbourne Institute of Technology

 

Abstract: 

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 patients 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.

Application of Integrated Computational Materials Engineering to the Design of New High Performance

Jason T. Sebastian, Ph.D.

Manager of Technology and Product Development

QuesTek Innovations, LLC

 

Abstract:

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.

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.
