Abstract
Ti-Mo-(33-80)mass%TiC alloys were prepared through P/M technology and their micro-structures and mechanical properties were investigated. These alloys were revealed to have two phases, those were TiCx phase and β-Ti phase. The lattice constant of TiCx was increased with increasing TiC content, associating with increase of x. On the other hand, increase of TiC content decreased the lattice constant of β-Ti due to increase of Ho content in β-Ti. Furthermore, increase of TiC content increased hardness of the alloys but slightly decreased transverse-rupture strength. It was concluded that Ti-Mo-45mass%TiC alloy had better combination of hardness and transverse-rupture strength than that of conventional Ti-Mo-33mass%TiC alloy.
