Microstructure and mechanical properties of WC-(Ti,M)(C,N)-Co cemented carbides with different nitrogen contents
文献摘要：
Three kinds of(Ti,M)(C1-x,Nx)(M=Ta,Nb,W)quaternary solid-solution powders with various nitro-gen contents were synthesized by carbothermal reduction-nitridation(CRN)process.Effect of nitrogen content on the microstructure and mechanical properties of WC-(Ti,M)(C1-x,Nx)-Co cemented carbides fabricated by sinter-hot isostatic pressing(HIP)were systematically investi-gated in this paper.The results show that the nitrogen content in the carbonitride raw powders strongly influences the morphology,the grain size and the compositions of the cemented carbides.All the cemented carbides with differ-ent nitrogen contents have a similar microstructural appearance:weak core-rim structure consisting of solid-solution phase embedded in WC-Co system.It is also observed that the carbonitride solid solution could some-what reduce the WC grain growth,and the effectiveness of refining and the rim thickness are sensitively related to the nitrogen content of(Ti,M)(C1-x,Nx)solid solutions.In addition,with an increase in the nitrogen content,mechanical properties of these hard metals are enhanced,which were discussed in terms of the constituent,the microstructure and the solution behavior of the carbonitride solid solutions.
