Previous　studies　have　reported　that　high　carbon　contents　in　FeCoCrNiMn　high-entropy　alloys　lead　to　carbides　precipitating　from　the　alloys.　Typically,　carbides　are　used　to　improve　the　strength　of　alloys　but　also　lead　to　decreased　ductility.　However,　the　strength　and　ductility　of　alloys　can　be　improved　when　carbides　shape,　size　and　distribution　are　carefully　controlled.　Therefore,　a　carbide-containing　FeCoCrNiMn　alloy　with　2　at.-%　carbon　was　prepared　by　arc　melting,　and　its　microstructure　and　mechanical　properties　were　further　tuned　by　cold　rolling　with　subsequent　annealing　treatment.　The　yield　strength　and　uniform　elongation　of　the　resultant　alloy　were　excellent,　reaching　581　MPa　and　25%,　respectively,　due　to　the　additive　combination　of　various　strengthening　mechanisms,　such　as　solid-solution　hardening,　grain-boundary　hardening　and　precipitation　hardening.　©　2017　Institute　of　Materials,　Minerals　and　Mining.
