摘要：

This　study　was　focused　on　the　effect　of　VC　addition　on　the　microstructure　and　mechanical　properties　of　the　prepared　ultrafine　grained　cemented　carbides.　VC　was　added　to　the　rawoxide　materials　which　were　synthesized　to　the　WC-Co　composite　powder　by　the　in-situ　reduction　and　carbonization　process.　The　ultrafine　grained　WC-Co　alloys　were　fabricated　by　the　spark　plasma　sintering　technique　using　the　prepared　WC-Co　composite　powder.　The　phase　constitution,　microstructure　characteristics　and　mechanical　properties　of　the　sintered　ultrafine　grained　cemented　carbides　were　analyzed　quantitatively.　The　study　proposed　that　VC　plays　a　significant　role　in　decreaseing　the　grain　size　of　the　prepared　WC-Co　alloy.　The　ultrafine　grained　WC-Co　alloy　with　high　comprehensive　properties　can　be　obtained　as　an　appropriate　addition　of　VC　in　the　developed　process.　©　(2014)　Trans　Tech　Publications,　Switzerland.
