The AlCoCrFeNi high-entropy alloys (HEAs) were prepared by the copper mold casting and Bridgman solidification. X-ray diffraction (XRD) results verify that the main phase was body-centered-cubic (bcc) solid solution by these two solidification processes, indicating its good phase stability. Interestingly, the metallographic photos show a morphology transition from dendrites to equiaxed grains after Bridgman solidification, which was considered to have a strong dependence on the parameter of the G/V (the temperature gradient to the growth rate ratio). Compared to the as-cast sample, the plasticity of alloys synthesized by Bridgman solidification was improved by a maximum of 35 pct.
