| 中文摘要 | Hafnium carbide/tungsten (HfC/W) cermets were prepared by an in situ reaction sintering process, using hafnium oxide (HfO2) and tungsten carbide (WC) as the raw materials. The reaction path, densi？cation behavior, microstructure develop- ment, and mechanical properties of the cermets were compre- hensively investigated. It was found that WC decomposed to tungsten semicarbide (W2C) and tungsten (W) in sequence, and meanwhile HfC was formed by carbothermal reduction between HfO2 and as-released carbon from the dissociation of WC. The solid solution formation between HfC and W during sin- tering was also studied. The obtained cermets (>98% TD) have a Vickers’ hardness of 8.16 GPa, a fracture toughness of 14.45 MPa m1/2 , and a high ？exural strength of 1211 MPa. |
