摘要(Abstract)：

采用EBSD技术研究了某钢厂厚板坯流程试制的50W270高牌号无取向硅钢980℃常化过程中显微组织及织构的演变。结果表明:常化过程是热轧板再结晶及晶粒长大的过程,常化使组织均匀化,但厚度方向上始终存在织构梯度。常化过程中再结晶初期形核主要发生在s=0.5层中的{116}<110>变形晶粒上,新晶粒主要织构为{116}<110>~{001}<110>,再结晶后期形核主要发生在旋转立方织构变形晶粒上,与热轧板织构的区别是s=0.5层出现较强的高斯织构。再结晶形核阶段符合亚晶聚合机理,织构的演变可以解释为再结晶阶段的特殊取向的择优形核和晶粒长大阶段的特殊取向晶粒择优长大。
