采用浮区法制备了Al0.3CoCrFeNi高熵合金单晶，并对其变形行为进行了研究。在873K和1073K时，合金中的Al原子在动态应变时效过程中起着重要的作用。Al0.3CoCrFeNi单晶在(1+1+1)面上也观察到明显的平面滑移。
Single crystals of Al0.3CoCrFeNi high entropy alloy were prepared by the floating zone method and the deformation behavior was examined. Dynamic strain aging accompanied by a serrated flow was found to occur in the single crystals at 873 K and 1073 K. Al atoms in the alloy played an important role in the dynamic strain aging. Distinct planar slip on (1 1 1) plane was also observed in Al0.3CoCrFeNi single crystals.
