Effect of Immediate Quenching after As-sintered on Microstructure of WC Phase and Strength of WC-1 4mass%TiC-8mass%Co

Abstract

WC-14%TiC-8%Co cemented carbide of as-sintered was immediately quenched. In comparison with conventionalsintered specimen, the strengths of the quenched cemented carbides were increased by20.2%-32.8%. It was ascribed that the formation of the slip steps on WC grain's edge is induced by thermal-stresses during quenching.
