Effects of Grain-growth Inhibitors on the Properties of Ultrafine WC-8%Co Cemented Carbide AITranslate
Abstract AITranslate
The effects of VC and Cr3C2 inhibitors against grain growth on the metallographical structure and mechanical property of ultrafine WC-8%Co cemented carbide were investigated systematically, and the two inhibitors were added separately or together. The results show that the hardness of WC-8%Co increases with the more dosage of inhibitors,but corresponding inhibitor composition point exists with the maximum bend strength and fracture toughness. WC-8%Co-0.2%VC-0.6 %Cr3C2 ,obtained by adding VC and Cr3C2 together,is of excellent comprehensive performance,and its HRA hardness is 92.9 ,bend strength σbb 4 370 MPa and fracture toughness KIC 9.1 MN^3.2.
