A novel supersaturated medium entropy alloy with superior tensile properties and corrosion resistance

We introduce a novel stainless equiatomic FeCrNi medium entropy alloy (MEA) with improved tensile properties and corrosion resistance. This alloy exhibits superior tensile properties with yield strength of 644 MPa, ultimate tensile strength of ~1.03 GPa and ductility of ~54 %, mainly owing to the multiple deformation mechanisms including nanotwinning, deformation induced phase transformation and solution strengthening of intersitial elements....
