Abstract

Abstract

93W-5.6Ni-1.4Fe cemented carbides were sintered by spark plasma sintering method, in which the sintering temperature ranged from 1100℃ to 1180℃ and the holding time was 5 min. The properties such as density, hardness and bending strength of the samples sintered at different temperatures were tested, and field spray scanning electron microscopy was used to investigate their appearance and rupture behavior. The results showed that 93W-5.6Ni-1.4Fe cemented carbides with high density were sintered by SPS at low temperature. Besides grain size could be controlled, the hardness and the bending strength could also be improved.
