中文摘要	the Ti(C,N)-based cermets were fabricated with ultrafine Ti(C,N) powders and metal binders Mo and Ni, in which the ratio of Mo to Ni was 1: 1 and total metal content ranged from 10wt% to 20wt%. The specimens were first CEP and pressureless sintered at various temperatures ranged from W1450degreesC to 1600degreesC and then treated at W1350degreesC for 20mins by HIP at the pressure of 140MPa. Results revealed that Post-HIP treatment could dramatically improve the density of specimens if their densities after pressureless sintering could reach the required standard. At the same sintering temperature, the grains became finer with increasing metal contents. The grain sizes increased dramatically with increasing sintering temperature from 1550degreesC to 1600degreesC. Compared to those obtained by hot pressing, the cermets obtained by pressureless-HIP sintering had better mechanical properties.
