摘要：Ti(C,N)-TiB2-WC composite ceramic tool materials with sintering aids such as Ni and Mo were fabricated at a temperature of 1550 degrees C for 1 h sintering duration time in vacuum by a hot-press technique. The microstructure and mechanical properties were investigated. The composite ceramic tool materials were analyzed by means of scanning electron microscope (SEM), X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). The main phases were composed of Ti(C, N), TiB2, WC and MoC, which indicated that no severe chemical reactions occurred in the composite. The flexural strength, fracture toughness and hardness of Ti(C,N)- 20 wt.%TiB2-WC ceramic material were 795.7 MPa, 6.4 MPa.m(1/2) and 19.2 GPa respectively.
