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. (C) 2015 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
