摘要

Numerical modeling of texture evolution during accumulative roll-bonding (ARB) is challenging, since ARB is a discontinuous process and cutting-stacking is involved in each ARB cycle. In this study, experimental techniques and crystal plasticity modeling were used to study the texture evolution after ARB. Commercial purity aluminum was ARB-processed up to 5 cycles, and X-ray diffraction and electron back scatter diffraction were used to characterize the bulk and through-thickness texture, respectively. Crystal plasticity finite element method (CPFEM) was also adopted to model the texture evolution. The history of texture evolution was traced in the CPFEM simulations, and the preservation, formation, and destruction of shear texture and rolling texture were revealed. The behavior of texture transition was investigated, and it was represented by the change in area fraction and crystal rotation angles.
