| Abstract: | TiC-based cermets with 6 different components of Mo and Ni content were manufactured by powder metallurgy.The microstructure and fracture morphology were investigated by SEM,and the mechanical properties such as transverse strength,fracture toughness and hardness were measured.The result shows that after addition of Mo,TiC-based cermets is a typical core-rim structure and the TiC grain is refined.When the contend of TiC is 70%,Ni∶Mo=2∶1,the properties of transverse strength,hardness and fracture toughness of the material are the best： 1362 MPa,92.4HRA,14.8 MPa·m1/2. |
