Ti(C,N)-xWC-Ni-Mo-C cermets with different WC contents were prepared by powder metallurgy.Microstructure,fracture morphology and crack propagation path were analyzed by SEM.The results show that the cermets contain black core-gray rim microstructure,as well as white core-gray rim microstructure.The grains are refined with appropriate WC addition,while the grains grow up with 20% WC.The main fracture models of the cermets are intergranular fracture and transgranular fracture.Crack bridging,crack deflection and microcrack occur during crack propagation.
