AbstractHigh-entropy alloys (HEAs) have displayed numerous unique features, however, high strength and high ductility are still the urgently desired mechanical property. The current study reports an outstanding combination of high strength and excellent ductility achieved in a eutectic high-entropy alloy (EHEA) AlCoCrFeNi2.1. The great achievement relays on a dual-phase heterogeneous structure strengthened with nano-precipitates. The heterogeneous structure provides the alloy a good combination of strength and ductility, and nano-precipitates in both of the face-centered cubic (FCC) and B2 phases generate an extra significant contribution to strength.
