Single crystals of 3% silicon iron and 17% chromium iron alloys with a common [11^^-0] axis parallel to the rolling direction and with a rolling plane rotated about this axis from (001) plane through angles, θ, equal to 35, 43, 45, and 55 degrees were cold rolled by 60, 70 and 80% and annealed at 600, 700, 800, and 1100℃. After cold rolling, initial orientations are macroscopically maintained. In the substructures of cold rolled matrixes, the small abnormal regions in which deformation proceeds by single slipping on the particular one of the slip systems having high Schmid factors are observed. The frequency of the formation of these abnormal regions is higher as θ of crystals and/or the reduction of cold rolling are increased. The primary recrystallization textures of the crystals are approximately {011}<100> or {011}<21^^-1>, and the sharpness of {011}<100>texture becomes maximum in the 3% silicon iron crystals of θ equal to about 45°, cold rolled 60% and annealed at 600℃. In the very early period of annealing, {011} recrystallization embryos are observed in the abnormal regions mentioned above.
