Evolution of texture during cold -rolling of a CrCoNi medium -entropy alloy

The microstructure and texture evolution of an equiatomic CrCoNi medium-entropy alloy during coldrolling has been investigated. For this purpose, the alloy has been rolled up to a true strain of about 2.3. The microstructure evolution during rolling reveals that mechanical twinning contributes to deformation. With increasing rolling reduction the alloy shows a gradual development of a a-fiber type texture. The experimental texture evolution is compared with the visco-plastic self-consistent (VPSC) model simulations taking into account twinning. The simulated textures show a continuous development of a alpha-fiber in agreement with experiment. (C) 2019 Elsevier Ltd. All rights reserved.
