Abstract

The correlation among the strength, ductility and precipitates in a dual-phase Al0.5CoCrFeNi high-entropy alloy has been investigated. The property of plastic was improved in the recrystallized Al0.5CoCrFeNi HEA prepared as the master alloy. Formation of the stable nanosized L12 phases after aging at 650 °C was revealed, along with the lath-like BCC phases precipitated in the grain, as the primary contribution of the strength enhancement. Excellent balanced tensile properties at room temperature were achieved through aging treatment, as the yield strength and ultimate tensile strength show 2.68, 1.63 times higher in 650 °C/140 h aged condition than that in initial states, respectively, superior to many high-entropy alloys and conventional alloys.
