摘要：
Ti(C, N)-based cermets was obtained by the low pressure sintering technology. The microstructure , phase of the Ti(C, N)-based cermets were studied by using scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD), and compared the mechanical properties. The experiment results show that, the mainly microstructure of alloy was black core-white rim, there were only two phase existed are (Ti, W, Mo, Ta)(C, N) and Co/Ni; with sintering temperature improved, the structure of alloy gradually uniformed, fracture toughness and hardness of Ti(C, N)-based cermets presented the trend of improving first and then reducing. Synthetical properties were best sintered at 1450°C, fracture toughness was 1774MPa, Hv is 1628MPa.
