Abstract

Direct-current treatment (DC-treatment) was employed to tune the microstructural evolution of deformed Al_0.1CoCrFeNi high-entropy alloy (HEA) in this paper. The time that partial recrystallization required during the DC-treatment is far less than that of conventional annealing at similar temperatures. The observation of dislocations configuration and stacking faults confirmed that the accelerated effect of DC-treatment on the promoted recrystallization of deformed Al_0.1CoCrFeNi HEA, especially the distinct role of the athermal effect. Besides, results of EBSD and GND density also evidence the promoted recrystallization and the corresponding dislocations distribution under DC-treatment.
