Twin orientations in channel die compression tests were determined by means of X-ray diffraction and EBSD techniques in 2 alloy samples having different initial textures. The measured orientations were compared with those calculated from various twin variants and initial orientations. The twin strain tensor of each twin variant was also calculated. It was demonstrated that the twin variant, which led to the basal orientation, best fitted the externally imposed strain tensor, and was the first to be activated. Texture evolution was explained in terms of a competition between twinning and prismatic slip.
