Magnetic, electrical and mechanical properties of Fe40Mn40Co10Cr10 high entropy alloy

Abstract A prototypical, single-phase, and non-equiatomic high entropy alloy Fe40Mn40Co10Cr10 has been mechanically deformed at room and cryogenic temperatures. Plastic deformation was accommodated via crystallographic slip at room temperature while transformation induced plasticity (TRIP) has been...
