Abstract

This work provided the interpretation of grain fragmentation behaviour of ferritic steel induced by texture transformation during rolling process. Ferritic steel was subjected to differential speed rolling (DSR) with sample rotation of 180 deg along rolling direction between passes. Electron back-scatter diffraction analysis on sample with speed ratio of 1:4 (lower:upper roller) showed that the grains with {001} ⟨ 1 1 ¯ 0 ⟩ orientation partially rotated into {111} ⟨ 1 ¯ 1 ¯ 2 ⟩ orientation, which lead to grain fragmentation.
