Abstract

The hardness, transverse-rupture strength (TRS), deformability, etc. of TiC_0.7N_0.3- and TiC_0.5N_0.5-Mo alloys vacuum-sintered and then HIP-treated were studied mainly in the temperature range from 1073 K to 1273 K, comparing with those of Ti(C,N)-Mo₂C-Ni alloys. The decrease in the hardness and TRS of Mo bonded alloys with increasing test temperature was markedly suppressed. The alloys containing 20∼40 vol%Mo showed at 1273 K the values of hardness and TRS as high as 600∼800 Hv and 0.9∼1.2 GPa, respectively, with a extremely high resistance to deformation. Therefore, the Mo bonded alloys were considered to be of importance for the special tool materials, when coated with the layer having high resistance to oxidation.
