Sintered (Ti,W)C carbides

Sintered (Ti,W)C carbides were prepared from (Ti,W)C solid solution powder at 1510 °C. The powder was produced by milling a mixture of carbon and oxides and then reducing it at 1200 °C for 1 h. The sintered (Ti,W)C carbides demonstrate full density, excellent hardness and fracture toughness values (ρ: 98–100%, HVN: 19–21 GPa, KIC: 6.4–7.7 MPa m1/2). These homogeneous (Ti,W)C carbides have considerable potential for use in structural applications.
