Unlike conventional alloys, high-entropy alloys (HEAs) have no single dominant element and typically use five or more metals mixed in roughly equiatomic proportions. This group of alloy is also referred to as multi-principal element alloys (MPEA) or complex concentrated alloys (CCA). HEAs can exhibit exceptional materials properties. In this work, a separate melting method was employed to cast large ingots of Al-contained HEAs such as AlCoCrFeNi and AlCoCrFeNi2.1. The HEA samples were subsequently processed through forging, hot rolling, and vacuum arc remelting to explore new microstructures and material properties.
