Powder metallurgy (P/M) is an attractive method to reduce the cost of titanium components provided a low cost powder supply can be developed; One low-cost powder under development is titanium hydride. In the present study 98+% dense compacts of Ti-6Al-4V alloy were produced by blending titanium hydride with elemental powders and consolidating with conventional press-and-sinter techniques. The compacts were evaluated for microstructural homogeneity, residual hydrogen, mechanical properties including fatigue and tension tests, and uniformity of density. The advantage of hydrogenated titanium approach in attaining uniform high relative density and sufficient tensile and fatigue properties for P/M titanium components will be discussed.
