Effect of Vacuum Sintering Temperature on Microstructure and Mechanical Properties of WC-8%Ni Cemented Carbide AITranslate
Abstract AITranslate
The influence was investigated of vacuum sintering temperature on the microstructure and me- chanical properties of WC-8% Ni cemented carbide by using scanning electron microscope, metallographic microscope, X ray diffractometer, microhardness tester and other devices. The results show that WC-8% Ni cemented carbide sintered in vacuum at 1 450 ℃ has the most excellent mechanical properties with the rel- ative density of 99.81% ,HV30 hardness of 13.23 GPa and fracture toughness （Kic） of 24.22 MPa · m1/2. Based on Murakami etching and XRD detection,the alloy sintered at 1 475 ℃ or more has η phase. And the effect is also discussed of η phase on alloy mechanical properties.
