Ti and Ti alloys show superior properties of lightweight, high strength and corrosion resistance, etc. Since Ti is very active at high temperature, the mechanical properties may be poor due to the oxygen and carbon contamination caused by type of substrate at high temperature and long time sintering. In this study, the effects of substrate for sintering on the mechanical properties of injection molded Ti-6Al-4V alloy were investigated using two types of substrates such as ZrO₂ and Y₂O₃ (as-received or baked in vacuum).<BR>The relative density, microstructure and hardness of sintered compacts were changed hardly, but the tensile properties were changed by baking treatment and type of substrate for sintering. The oxygen content of the sintered compacts by using as-received ZrO₂ substrate increased with increasing sintering time, then the elongation of the compacts were reduced. While the compacts using the baked ZrO₂ and Y₂O₃ substrates showed good tensile properties because of low carbon and oxygen content.
