The　stress-strain　behaviors　of　WC-Co　cermets　with　various　binder　contents　were　investigated,　in　which　the　residual　thermal　stress　(RTS)　was　taken　into　account.　The　effects　of　binder　content　and　WC　grain　morphology　on　the　RTS　and　strain　responses　under　applied　stress　were　quantified　by　finite　element　modeling　based　on　the　real　microstructures　of　cermets.　It　shows　that　the　RTS　of　both　the　hard　matrix　and　ductile　binder　phases　are　linear　functions　of　the　binder　content.　High-level　RTS　is　concentrated　in　the　WC　region　close　to　WC/WC　grain　boundaries　adjacent　to　the　Co　phase,　and　in　the　Co　region　close　to　the　WC/Co　interface,　respectively.　In　the　cermets　with　RTS,　the　accumulation　rate　of　strain　partitioning　and　strain　localization　in　WC-Co　cermets　decreases　with　the　decrease　of　Co　content.　It　is　found　that　increasing　the　proportion　of　thin　Co　layers　parallel　to　the　compression　direction　is　beneficial　to　simultaneously　strengthening　and　toughening　cermets　with　low　Co　contents.　This　study　provides　access　and　mechanisms　for　modulating　RTS　distribution　to　achieve　excellent　comprehensive　mechanical　properties　of　cermets　with　various　binder　content.
