The ITA, organiser of Titanium 2012, 7-10 October, Atlanta, USA, has announced that the Powder Metallurgy session at this year’s conference will be sponsored by Advanced Materials (ADMA) Group Inc., USA.
One of the papers during the session, entitled “Transformational Non-Kroll Process Hydrogenated Titanium Powder Production” will profile ADMA’s non-Kroll process for manufacturing hydrogenated titanium sponge and powder. ADMA has designed and installed a laboratory scale titanium powder-manufacturing unit that has produced ADMA Hydrogenated Titanium Powder (ADMA TiH2).
ADMA will describe how hydrogenated titanium sponge, produced by the company’s technology, can be easily ground into powder for the production of commercially pure titanium or any titanium alloy components via “Blended Elemental Powder Metallurgy.”
The presence of hydrogen during the sintering phase results in titanium components with very low interstitial content that easily meet and surpass ASTM and AMS requirements, the company stated. In addition, because of their high purity and low interstitial content, ADMA TiH2 powder components can be welded; something that, until now, hasn’t been achieved by a low-cost, powder-metal titanium process. ADMA executives also will outline current developments in the design and installation of a pilot-scale hydrogenated titanium powder production system.
Another presentation, “Powder Metallurgy Titanium and Titanium Alloy Components Manufactured from Hydrogenated Ti Powder,” will discuss low cost, room temperature, powder metallurgy solid-state consolidation processes, including die pressing, direct powder rolling, and cold-isostatic pressing, followed by vacuum sintering, to produce a broad range of titanium and titanium alloy components from ADMA TiH2.
Several high-performance, finished components for critical applications, along with details on their mechanical properties, chemistry and microstructures, will be presented. Company officials will show the transformational, low-cost, Powder Metallurgy manufacturing of commercially pure titanium and titanium alloy components from ADMA TiH2 powder brings improved performance to critical industrial applications. According to ADMA, extensive testing has consistently demonstrated material properties that are equal or superior to those obtained via conventional titanium ingot metallurgy.
Another presentation in the Session will demonstrate various Titanium alloys produced by the Blended Elemental Powder Metallurgy (BEPM) approach can be effectively heat treated to the strength levels achieved by ingot metallurgy STA alloys of identical composition. Analysis of the post-sintering treatments and response of the BEPM Titanium alloys to heat treatment will be discussed. The results obtained on high strength alloys widely used in the aerospace industry such as Ti-10V-2Fe-3Al and Ti-5Al-5Mo-5V-3Cr will be presented.
Dr Colin McCracken, Technical Director for AMETEK – Reading Alloys will be participating in the session giving a presentation on Plasma Spheroidized (PS) Titanium Powders. Reading Alloys has developed a new Plasma Spheroidized (PS) Titanium powder that incorporates a spheroidization process step, which produces a cost effective high tap density titanium powder. This free flowing powder also exhibits no satellites and/or particle agglomerates. Dr McCracken’s presentation will outline the manufacturing route and key powder characteristics of a spherical titanium powder derived from a hydride-dehydride powder.
