Single crystal sheets of a 3%Si-Fe alloy were cold-rolled in approximately (100)[001] orientation to 50 and 70% reductions in thickness. The orientation change during rolling and the relationship between the deformation texture and the annealing texture were studied. The behavior of crystal during rolling depends on the degree of slight asymmetry in the initial orientation. A clockwise rotation around the [110] axis occurs in the 50% rolled crystal, while both counterclockwise and clockwise rotations around the sheet normal are observed in the 70% rolled crystal. The primary recrystallization texture of the 50% rolled crystal consists of one preferred orientation, which can be derived from the deformation texture by a counterclockwise rotation of approximately 25° around the [110] axis. Four components of the primary recrystallization texture of the 70% rolled crystal can be related to two components of the deformation texture by rotations of 25° around the [110] and [1\={1}0] axes. In agreement with Hsun Hu’s proposition the results can be interpreted on the basis of the oriented growth theory, in wich, however, the growth velocity of a recrystallized grain is supposed to be determined by the directional arrangement of imperfections in the deformed matrix. A selective growth of grains oriented near (100)[001] occurs by the secondary recrystallization on annealing the 70% rolled crystal above 850°C.
