Abstract
Ti-8.4vol%M-47.4vol%TiC (M: Cr, Mo, W) alloys were prepared through P/M technology and their microstructures and mechanical properties were investigated. It was revealed that Ti-Cr-TiC alloy (Cr alloy) had 3 phases, which were TiC, α-Ti and β-Ti, Ti-Mo-TiC alloy (Mo alloy) had 2 phases, which were TiC and β-Ti and Ti-W-TiC alloy (W alloy) had 3 phases, which were TiC, β-Ti(Ti rich) and W(β-Ti type, W rich). It was noted that TiC grain size of W alloy was much smaller than that of both Cr alloy and Mo alloy. It was found that hardness and transverse-rupture strength of W alloy were much higer than those of both Cr alloy and Mo alloy.
