| 摘 要： | 采用Zeiss光学显微镜及X射线衍射仪对含铜低温取向硅钢生产过程中热轧、一次冷轧、脱碳退火和二次冷轧阶段的显微组织与织构的演变规律进行了研究。结果表明:热轧试样的组织与织构在厚度方向上呈现明显的梯度变化,试样的表层和过渡层发生再结晶,过渡层存在较强的Goss织构,中心层存在以{001}<110>为主的强α织构。一次冷轧后试样组织被轧制成沿轧向分布的纤维状组织,织构以强α和弱γ织构为主。脱碳退火后试样发生再结晶,晶粒平均尺寸为15.69 μm,总体织构强度有所减弱,但Goss织构强度升高。二次冷轧后组织由等轴晶粒变为纺锤状组织,织构以弱α和强γ织构为主,其中{111}<112>强度最高。

| Abstract: | Microstructure and texture evolution of Cu-containing low temperature oriented silicon steel during hot rolling, first cold rolling, decarbonization annealing and second cold rolling were studied by Zeiss optical microscope and X-ray diffraction. The results show that the microstructure and texture of the hot rolled specimen show obvious inhomogeneity in thickness direction. The surface and transition layers of the specimens is recrystallized, the transition layer has strong Goss texture, and the central layer has strong α texture dominated by {001}<110>. After first cold rolling, the microstructure of the specimen is compressed into a fibrous structure distributed along the rolling direction, and the texture is mainly strong α texture and weak γ texture. The recrystallization occurs after decarbonization annealing, the average grain size is 15.69 μm, and the overall texture intensity decreases, but the Goss texture intensity increases. After second cold rolling, the microstructure changes from equiaxed grain to spindle structure, and the texture is mainly weak α and strong γ texture, of which {111}<112> has the highest intensity. |
