研究了WC-Fe-Al、WC-Co-Al和WC-Ni-Al合金的致密化行为和高温抗氧化性能。WC-11.2mass%Ni-0.7mass%Al合金致密化良好，抗弯强度为2.1GPa，硬度为HRA 89.8，WC-12.8mass%Fe-0.7mass%Al合金在1073 K空气中加热时的增重与WC-8.6mass%Fe-1.4mass%Al合金相同，Al合金和约一半的WC-12.8mass%Co合金。
The densification behaviour and high temperature oxidation resistance of WC-Fe-Al, WC-Co-Al and WC-Ni-Al allloys were studied.WC-Co-Al alloy has poor sinterability. WC-11.2mass%Ni-0.7mass%Al alloy was densified perfectly and has transvers-rupture strength of 2.1 GPa, but has hardness of HRA 89.8, which is less than that of WC-8.6mass%Fe-1.4mass%Al alloy.The weight gain of WC-12.8mass%Fe-0.7mass%Al alloy heated in air at 1073K was same as that of WC-8.6mass%Fe-1.4mass%Al alloy and about a half of that of WC-12.8mass%Co alloy.
