Annealing twins are frequently observed in fcc metals of low or medium stacking fault energy although their occurrence in aluminium is comparatively rare as discussed in the early review of twinning by Cahn. Twins have been observed both in recrystallized and vapor deposited aluminium, which suggests that they may be formed during either recrystallization or grain growth. Little significance was attached to annealing twins in aluminium until an extensive research project in Gittingen into the origin of recrystallization textures produced evidence of extensive twin formation during the early stages of recrystallization of several fcc metals including aluminium. As the twinning generated grains of new orientations, which were often observed to have more favorable orientations for growth than the original recrystallization nuclei, it was proposed that twinning is an important factor in determining recrystallization textures.
