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. 展开更多

Thin-gauge non-oriented electrical steel sheets of 0.2 mm in thickness with high magnetic induction and low core loss were produced by a two-stage cold-rolling method with and without normalization annealing.The through-process texture evolutions of the two processes were compared and studied by means of X-ray diffractometer and electron backscattered diffraction.Results showed that excellent magnetic properties were attributed to strong η-fiber recrystallization texture in the final sheet.Coarse γ-fiber-oriented grains after intermediate annealing and medium cold-rolling reduction were considered key factors to obtain a strong γ-fiber texture given that a large number of shear bands within the γ-fiber deformed matrix provided dominant nucleation sites for η-fiber-oriented grains.The normalization annealing after hot rolling was favorable for the retention of cube texture,thereby decreasing the magnetic anisotropy of thin-gauge non-oriented electrical steels. 展开更多
