摘要：

The　present　study　was　focused　on　the　subsequent　heat-treatment　of　the　in-situ　synthesized　WC-Co　composite　powder　and　its　effect　on　the　properties　of　the　cemented　carbides　prepared　by　sinter-HIP.　The　element　composition,　phase　constitution,　microstructure　characteristics　and　properties　of　the　prepared　cemented　carbides　were　analyzed　quantitatively.　The　heat-treatment　of　the　composite　powder　before　sintering　plays　a　significant　role　in　the　characteristics　of　the　microstructure　and　properties　of　the　WC-Co　bulk　material.　The　optimized　heat-treatment　parameters　for　the　composite　powder　were　obtained,　from　which　the　excellent　combination　mechanical　properties　were　achieved　for　the　sintered　WC-Co　bulk　material.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
