Abstract AITranslate

Study is made of the effects and effecting mechanisms of a new type of grain growth inhibitor on vacuum sintering behavior of nanometer cemented carbide.The results show that the new grain-growth inhibitor can improve sintering densification process.The addition of the new grain-growth inhibitor into traditional transitional element carbides,resulteding composite inhibitors,which are much more effective and can induce oriented WC grain growth obviously during sintering.For WC-10Co-0.8VC/Cr_3C_2 powders with 0.1% mass content of the new additive,the density of 14.48 g/cm^3 can be achieved after sintering at 1 375 ℃ for 30 min, corresponding to the grain size of 160 nm and the micro-hardness of 2 150 MPa.
