FeCoCrNiMn　high-entropy　alloys　were　produced　by　mechanical　alloying　(MA)　and　vacuum　hot　pressing　sintering　(VHPS).　Results　showed　that　the　nano-crystalline　alloy　powders　were　obtained　by　MA　and　the　corresponding　phase　structures　were　composed　of　FCC　matrices　and　low　amounts　of　BCC　and　amorphous　phases.　After　VHPS,　the　BCC　phases　almost　disappeared,　simultaneously　with　the　precipitation　of　sigma　phases　and　M23C6　carbides.　An　increase　of　sintering　temperature　resulted　in　grain　growth　of　the　precipitated　phases.　As　the　sintering　temperature　was　increased　from　700　to　1000　degrees　C,　the　strain-to-failure　of　the　alloys　rose　from　4.4%　to　38.2%,　whereas　the　yield　strength　decreased　from　1682　to　774　MPa.　The　bulk　FeCoCrNiMn　HEAs,　consolidated　by　VHPS　at　800　degrees　C　and　900　degrees　C　for　1　h,　showed　relatively　good　combination　of　strength　and　ductility.
