Asymmetric accumulative roll-bonding (AARB), combining asymmetric rolling and accumulative roll-bonding, has shown its capability in tailoring texture. In this study, the texture evolution in commercial-purity aluminum (AA1050) after AARB at room temperature was thoroughly investigated using crystal plasticity finite element method (CPFEM). The asymmetric ratios are 1.0, 1.1, 1.2, 1.3, and 1.5, and the AARB was conducted up to 3 cycles. The predicted texture was validated by experimental observations. The through-thickness texture was partitioned into rolling-type texture, shear-type texture, and random texture, and the texture transition between them was qualified. It was revealed that the through-thickness position plays a critical role in texture transition. The area fraction of shear-type texture increases with increasing asymmetric ratio and then decreases after reaching its maximum with asymmetric ratio of 1.3. The influence of asymmetric rolling ratios on the distribution of these texture components was systematically analyzed.
