Novel Co-rich high entropy alloys with superior tensile properties

We developed a series of Co-rich CoxCr25(FeNi)75−x (x = 35, 45, 55, 65) high entropy alloys with improved strength and/or ductility, derived from lowering the stacking fault energy (SFE) and reducing the fcc phase stability of the equiatomic CoCrFeNi alloy. Thermodynamics and ab initio calculations...
