Abstract：

Ultra-coarse　WC-Co　cemented　carbides　with　precipitated　(Zr,W)Cx　particles　in　ceramic　phase　were　prepared,　and　their　compression　behavior　and　mechanical　properties　at　different　temperatures　were　studied.　It　was　found　that　the　(Zr,W)Cx　precipitates　had　a　coherent　or　semi-coherent　interfacial　relationship　with　the　WC　matrix.　These　precipitates　strengthened　the　ultra-coarse　WC　grains　through　interactions　between　WC　dislocations　and　(Zr,W)Cx　particles.　This　strengthening　effect　is　especially　important　to　the　ultra-coarse　cemented　carbides　at　high　temperatures,　leading　to　an　increased　strength　compared　to　their　counterpart　under　same　testing　conditions.　©　2023　Elsevier　Ltd
