| Abstract: | The Ti（C,N）-based cermets were synthesized by powder metallurgy process.Effect of different powder size combinations of TiC and TiN on microstructure and properties of Ti（C,N）-based cermets was studied.The cermets were analyzed by means of XRD and SEM.The results show that Ti（C,N）-based cermets prepared with micron-scale TiC and nano-scale TiN exhibit the best mechanical properties.It＇s transverse-rupture strength and fracture toughness are up to 1 052.8 MPa and 9.3 MPa·m1/2 respectively. |
