摘要：

采用轧制工艺制备了0.10mm厚的6.5%Si高硅电工钢超薄带，并用X射线衍射技术对冷轧过程中的形变织构演变规律进行了研究，进而提出了分别有利于λ(<100>//ND，ND为轧面法线方向)和η(<100>//RD，RD为轧向)再结晶织构优化的形变织构控制方法.研究表明，50%~70%压下率有利于η再结晶织构优化，易于促进S=0.5层强η再结晶织构的形成.小于30%压下率和91%~97%压下率均有利于λ再结晶织构优化，其中30%的压下率更适合于二次冷轧法制备高硅钢超薄带时λ再结晶织构控制.

Abstract:

High silicon electrical steel ultra-thin sheets of 0.10mm thick， containing about 6.5% Si， were prepared by rolling method. The evolution of deformation texture during cold rolling was studied using X-ray diffraction. Then the methods of controlling deformation texture were proposed in favor of the λ (<100>//ND， normal direction) and η (<100>//RD， rolling direction) recrystallization texture， respectively. The rolling reduction between 50% and 70% is easy to promote the formation of the η recrystallization texture at the layer of S=0.5. While， the rolling reductions of either less than 30% or 91%~97% are in favor of λ recrystallization texture， in which the former reduction is more suitable to control the λ recrystallization texture when using a two-stage cold rolling method to prepare high silicon steel ultra-thin sheets.
