Abstract

© 2020 IOP Publishing Ltd. In this study, the crystal plasticity finite element method (CPFEM) was used to predict the texture evolution in a Goss (011)[100] aluminium single crystal after multi-pass reverse rolling and unidirectional rolling. Submodel was also used to improve the mesh resolution in a smaller region, by which micro-subdivision was successfully captured. After the predictions being validated by the experimental observations, the deformation behaviours were investigated, in terms of crystal rotation, shear strain, and slip system activity. Macro-subdivision occurred through the thickness by forming matrix bands. It was found that the deformation was unidirectional after unidirectional rolling and macro- and micro-subdivision were amplified with increasing reduction, while the previously developed deformation pattern was destroyed by the following pass of reverse rolling.
