Abstract：

FeCoCrNiMnTi0.1C0.1　(TiC10　alloy)high-entropy　alloy　(HEA)was　successfully　prepared　by　mechanical　alloying　(MA)and　vacuum　hot-pressing　sintering　(VHPS)at　different　temperatures　(850,　900,　950　and　1000　°C).　During　the　MA　process,　the　constituent　elements　were　gradually　alloyed　and　formed　FCC　solid　solutions.　The　microstructure　of　bulk　TiC10　alloy　is　mainly　composed　of　FCC　phase　as　the　matrix　phase　and　a　small　quantity　of　M23C6,　M7C3　and　TiMnO3　phases.　The　TiC10　alloy　has　relatively　good　comprehensive　mechanical　properties　when　sintered　at　900　°C.　The　yield　strength　and　hardness　of　the　alloy　reached　1652　MPa　and　461　HV,　respectively.　In　this　study,　a　close　relationship　between　microstructure　and　mechanical　properties　was　discussed.　Grain　boundary　strengthening　is　the　dominant　strengthening　mechanism.　©　2019
