Paper Title:
Study of Ti(C,N)-Based Cermets Fabricated by Pressureless-HIP Sintering
  Abstract

In this paper, 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 CIP and pressureless sintered at various temperatures ranged from 1450°C to 1600°C and then treated at 1350°C 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 1550°C to 1600°C. Compared to those obtained by hot pressing, the cermets obtained by pressureless-HIP sintering had better mechanical properties.
