在本研究中，采用金属注射成型工艺，以气体雾化获得的预合金Ti-6Al-4V粉末为原料，制备烧结钛合金压块。研究了烧结条件对Ti和60Al-40V混合粉末的密度、力学性能和氧碳含量的影响。预合金粉末注塑成型件的力学性能（抗拉强度为890 Mpa，伸长率为10%）可与JIS 60等级的变形Ti-6Al-4V材料相比较。在这种情况下，与使用预合金粉末的注塑件相比，使用混合粉末的注塑件具有高密度和高性能（相对密度为98%，抗拉强度为910Mpa，伸长率为14%）。
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.
