Unexpected Cube texture in cold rolling of copper

Cold rolling of high purity copper by 60-80% thickness reductions followed by quenching in ice water a recrystallization texture rather than a deformation texture was achieved. It was found that discontinuous dynamic recrystallization (DDRX) was responsible for nucleation of the new grains with Cube orientation at 60%, 70%, and 80% rolling reductions. In addition, with increasing rolling reduction, the recrystallization texture significantly decreased due to rotation of recrystallized grain towards deformation texture by slip.
