Single crystals of 3% silicon iron with a common axis of [11^^-0] parallel to the rolling direction and with rolling planes rotated about this axis from (001) plane through angles, θ, equal to 0, 13, 22, 28, 35, 43, 55, 64, 78, and 90 degrees, were cold rolled by 60 and 80% and subsequently annealed. After cold rolling, the initial orientations of the crystals of 0°⩽θ⩽55° are macroscopically maintained and the orientations of the crystals of 64°⩽θ⩽90°are rotated into (111)[11^^-0]∿[112^^-]. The feature of texture, the dislocation configuration and the hardness of cold rolled crystal can be explained semiquantitatively in terms of calculated shear and/or rotation components of the tensors of the displacement gradients. Primary recrystallization at 600℃ initiates earlier and proceeds more rapidly in a crystal as its initial orientation θ is approaching towards 90°. The crystals of 0°⩽θ⩽28° hardly recrystallize up to 1100℃ and large grains having a few restricted rotational orientation relationships with cold rolled matrixes grow at the edge parts of specimens annealed at 1200℃. On the other hand, the crystals of (1) 35°⩽θ⩽55° and (2) 64°⩽θ⩽90° recrystallize into the textures of (1) {011}<100> or {011}<21^^-1> and (2) {111}<uvw> preferred orientations, respectively, after annealing at 600℃.
