Behaviors of crystal reorientation and twinning during rolling were calculated using the crystal plasticity. The calculations were performed for several Ni alloys with different stacking fault energies. The calculation results were compared with EBSD observation of cold rolled samples of the Ni alloys. Large amount of deformation twinning was observed in the rolled Alloy C22 that has low stacking fault energy. Both the grains with twinning and the grains without twinning were observed in the rolled Alloy C22. These behaviors were successfully simulated by the crystal plasticity.
