Tensile properties of an AlCrCuNiFeCo high-entropy alloy in as-cast and wrought conditions

► Effect of extensive multistep forging on an AlCoCrCuFeNi high-entropy alloy. ► Coarse dendritic structure transforms into fine equiaxed duplex structure. ► Forged alloy was stronger and more ductile than as-cast alloy at room temperature. ► Alloy showed brittle to ductile transition in both conditions. ► Forged alloy showed superplastic behavior at high temperatures.
