Effect on the Microstructure and Properties of WC-10% Co Alloy Co-Doped with NbC and Cr₃C₂

Abstract:

In order to study the effect of co-doped with NbC /Cr3C2 on the properties of WC-10%Co alloy, the WC-10%Co alloys co-doped with different contents of NbC / Cr3C2 were produced with vacuum sintering furnace, and the microstructure and properties were also investigated by using different testing methods. The results showed that there existed a great improvement on the mechanical property of WC-10%Co alloy. With the co-doped 0.4% Cr3C2 / 0.3%NbC addition, the best strength properties that hardness was 1645 HV30 and transverse rupture strength was 1951 MPa were obtained when the sintering process was performed at 1400°C for 1.5 h.
