TITANIUM 2012 will be held from 7-10 October in Atlanta, Georgia, USA.
One paper on the panel is titled "Transformational Non-Kroll Process Hydrogenated Titanium Powder Production," and 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). Hydrogenated titanium sponge, produced by ADMA's technology, can be ground into powder for the production of commercially pure titanium or 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 says. In addition, because of their high purity and low interstitial content, ADMA TiH2 powder components can be welded.
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.
Another paper in the session will demonstrate various titanium alloys produced by the Blended Elemental Powder Metallurgy (BEPM) approach which can be effectively heat treated to the strength levels achieved by ingot metallurgy STA alloys of identical composition.
Dr. Colin McCracken, technical director for AMETEK - Reading Alloys, will also be participating in the session giving a presentation on plasma spheroidized (PS) titanium powders. Reading Alloys has developed a new PS titanium powder that incorporates a spheroidization process step, which produces a cost effective high tap density titanium powder.
