High Performance Titanium Powder Metallurgy Components Produced from Hydrogenated Titanium Powder by Low Cost Blended Elemental Approach
This paper presents the recent advances in titanium Powder Metallurgy (P/M) achieved by using hydrogenated titanium powder to produce highest quality components using the low cost blended elemental approach. The benefits of using hydrogenated titanium powder in the manufacture of P/M Titanium components,as compared to using commercially pure (CP) titanium powders in common use today,are demonstrated. The major factors contributing to the improvement in Titanium and Titanium alloy properties as a result of use of hydrogenated titanium powder are discussed,along with the role of hydrogen in the solid state sintering behavior of titanium hydride and master alloy powder blends. Mechanical and chemical properties of P/M Ti6A1-4V alloys meet ASTM (approximately 0. 3％ oxygen content),and AMS (below 0. 2％ oxygen content) specifications. The ability to achieve extremely low interstitials through solid state consolidation and sintering of hydrogenated titanium powder is explained. The superior mechanical properties and extra low interstitials in P/M alloys produced from hydrogenated titanium powder will contribute to a wider acceptance of the solid state powder metallurgy process and promote the use of PM titanium alloys in various critical applications.
