摘 要：The significant occupancy of {411}<148>texture exists in the thin-gauge grain-oriented silicon steel（TGCRGO is defined that thickness of the sheet is<0.25 mm and the reduction in cold rolling is more than 90%） which has been considered to have obviously effects on the abnormal growth of Goss-oriented grains during the secondary recrystallization process. The microstructures of the TG-CRGO were investigated by X-ray diffraction and electron back-scattered diffraction in this study. It was found that {411}<148>>texture mainly exists in the center layer of hot-rolled as well as normalized plates.With the increase in cold rolling reduction, {411}<148> orientation gradually rotates to a-fiber texture（<110>//RD）.Finally, few {411}<148>would retain at the boundaries of deformed a-fiber grains（<110>//RD） as the reduction in cold rolling reaches 90%. After annealing treatment, a small amount of c-fiber textures（<111>//ND） preferably nucleates and recrystallizes between the DBs（deformation bands） at first; then, the {411}<148> recrystallization texture occurs and mainly nucleates at the grains boundaries of the deformed a-fiber grains, and also quite a few {411}<148>orientation grains nucleate in the inner of {112}<110>grains. But this phenomenon was not observed in the {100}<011>deformation grains.With respect to the occurrence of {411}<148>recrystallization texture, it is mainly induced by strong a-fiber as well as weak c-fiber textures formed during cold rolling other than originating from {411}<148> regions in hot bands.
