Herein, four kinds of initial Goss textures with different deviation angles (0°, 5°, 10°, and 15°) are obtained by controlling the included angles between the longitudinal directions of rectangular cutting specimens and the initial rolling direction of the raw material. Then, 0.05 mm thick grain‐oriented silicon steels are fabricated by cold rolling and primary recrystallization annealing. Effects of initial textures on the microstructure and texture evolutions and magnetic properties are investigated in detail. Compared with sharp {111}<112> in the cold rolling sheet with initial exact Goss, the deviated Goss favors the formation of strong {111}<112> + weak {h11}<1/h 1 2> textures. After annealing, sharp {210}<001> + medium {110}<001> textures develop as a result of the small initial deviation, while larger initial deviations contribute to the {310}<001> texture. In addition, the average grain sizes are also related to recrystallization textures. Consequently, the distinct recrystallization microstructures and textures result in the differences of magnetic properties.

超薄晶粒取向硅钢中具有不同偏角的初始高斯取向与组织和织构演变的关系

在此，通过控制矩形切削试样的长度方向与原材料的初始轧制方向之间的夹角，可获得具有不同的偏离角度（0°，5°，10°和15°）的四种初始戈斯织构。。然后，通过冷轧和初次再结晶退火，制造出0.05毫米厚的取向硅钢。详细研究了初始织构对显微组织和织构演变以及磁性能的影响。与初始精确戈斯的冷轧薄板中的锋利的{111} <112>相比，偏离的戈斯有利于形成强{111} <112> +弱{h11} <1 / h 1 2>纹理。退火后，由于较小的初始偏差，形成了明显的{210} <001> +中等{110} <001>纹理，而较大的初始偏差会导致{310} <001>纹理。另外，平均晶粒尺寸也与重结晶织构有关。因此，独特的再结晶微结构和织构导致磁性能的差异。
