The significant occupancy of {411}\148[ texture exists in the thin-gauge grain-oriented silicon steel (TG-CRGO 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.
