In this study, the metal injection molding process was applied to produce the sintered titanium alloy compacts using pre-alloyed Ti-6Al-4V powders obtained by gas atomization. The effect of sintering conditions on the density, mechanical properties, and oxygen and carbon contents were investigated as compared to using mixed Ti and 60Al-40V powders. The mechanical properties (Tensile strength of 890 Mpa, Elongation of 10%) of injection molded compacts using pre-alloyed powder were comparable to the wrought Ti-6Al-4V material of JIS 60 grade. In such a case, the injection molded compacts using mixed powders showed high density and high properties (Relative density of 98%, Tensile strength of 910Mpa, Elongation of 14%) as compared to the compacts using pre-alloyed powder.
