Titanium and Titanium Alloy via Sintering of TiH₂

Abstract:

Blended elemental (BE) powder metallurgy (PM) is a promising low cost approach for manufacture titanium and titanium alloy components. Conventional BE method relies on sintering of pure titanium metal powder, while the new approach examined in this investigation produces bulk titanium materials by sintering titanium hydride powder. Dehydrogenation and densification of TiH2 powders with different particle sizes and TiH2-6Al-4V alloy powder was studied using thermogravimetric and dilatometric techniques. The results show that the dehydrogenation of TiH2 leads to very rapid shrinkage of α-Ti during sintering. In contrast, densification TiH2-6Al-4V requires dissolution of alloy elements which occurs during sintering above its beta transus temperature.
