Effects of(V,Cr,W)C Composite Powders on Microstructure and Mechanical Properties of WC-11Ni Cemented Carbides AITranslate
Abstract AITranslate
(V,Cr,W)C composite powders were prepared by carbothermal reduction method using Cr2O3,WO3,V2O5,and carbon black as raw materials at 1500℃for 2 h.The phase ingredients and microstructure of(V,Cr,W)C composite powders were characterized by XRD and SEM,and the effects of adding method and content of the composite powders on the microstructure and mechanical properties of WC-11Ni cemented carbides were investigated.The results show that the mechanical properties of the alloy are significantly improved by the addition of(V,Cr,W)C composite powders,and its flexural strength,Vickers hardness,and fracture toughness are increased by 19.97%,19.61%,and 12.18%,respectively,compared with those of the specimens without composite powders.The properties of the alloy with(V,Cr,W)C composite powders are better than those with(V,Cr)C composite powders and with WC+Cr3C2hybrid powders.In addition,the flexural strength,Vickers hardness,and fracture toughness of the alloy increase at first and then decrease with the increase of the addition of the(V,Cr,W)C composite powders.When the addition of the(V,Cr,W)C composite powders is 0.6%,the flexural strength,Vickers hardness,and fracture toughness of the alloy reach the maximum values of 2835 MPa,1671 MPa,and 15.1 MPa·m1/2.
