Microstructure and Properties Evaluation of WTi(C,N)-06 Cemented Carbide with TaC and NbC

摘要：

A Wti(C,N)-06 cemented carbide with TaC and NbC is studied as the research objective in this paper. The phase composition of the cemented carbide was analyzed by using XRD method, and the microstructure of the cemented carbide was studied and evaluated by using optical microscopy and scanning electron microscopy. According to the comparison with a general-grained cemented carbide, the addition of TaC and NbC can suppress the grain growth of WC crystal, and it is also good for improving mechanism performance. The average grain size of Wti(C,N)-06 cemented carbide is 2.1μm, density 12.9g/cm3, hardness 74HRC, and bending strength 2378MPa.
