High-entropy alloys (HEAs) feature unique properties distinguished from conventional alloys, yet achieving simultaneous high strength and ductility remains a significant challenge. This study introduces a novel strategy incorporating the eutectic alloy concept to overcome the limitations of HEAs, such as inferior castability and compositional segregation. We designed an AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA) characterized by a fine lamellar fcc/B2 microstructure, which demonstrated an exceptional combination of high tensile ductility and fracture strength at room temperature. Notably, the mechanical properties of this EHEA were maintained up to temperatures of 7006°C. This innovative alloy design approach holds promise for advancing the large-scale industrial production of HEAs that exhibit both remarkable fracture strength and ductility.
