The effects of Mo addition and sintering temperature on the microstructure and mechanical properties of（Ti,V,Mo）C-based cermets were investigated by BSE ＆ EDS,IPP,XRD and density,hardness,bending strength tests.The results show that the hard phase is constituted by black core phase and grey phase in（Ti,V,M）C-based cermets.Mo addition mainly contributes to form carbides solution in the hard phase.With increasing the sintering temperature,the proportion of black core phase decreases and the grey phase coarsens obviously,leading to the decrease of bending strength.（Ti,V,M） C-based cermet with favorable comprehensive properties can be obtained at 1 400 ℃ of sintering temperature with 6% of Mo addition.
