摘要:
This work aims to explore the effects of different sintering temperatures on microstructure, mechanical properties and magnetic properties of (Ti,W)C–xCoCrFeNiMo (wt%, x = 15, 30) cermets. Results showed that bending strength, hardness and fracture toughness of sintered cermets first increased and then decreased with the increase of sintering temperature. They reached peak values of about 967.2 MPa, 92.8 HRA and 9.1 MPa •m1/2 for x = 15, and 1278.3 MPa, 91.2 HRA and 13.6 MPa •m1/2 for x = 30, after sintering at 1450 °C, respectively. The Ms...
