Thermodynamics-based design strategy for optimizing strength and ductility of Cr-Ni-Mn-Fe medium-entropy alloys

•First ever preparation of stacking fault energy maps (SFE maps) for the Cr-Ni-Mn-Fe MEA alloy system, applicable to various temperatures.•The most balanced tensile properties can be achieved by designing alloys with an SFE value adjacent to the TWIP-TRIP boundary line in the SFE maps.•Cr12Ni12Mn16F...
