利用X射线衍射及EBSD取向成像技术考察了电工钢初始柱状晶组织在热轧、冷轧、退火过程中的组织及织构演变规律,分析了立方取向和旋转立方取向晶粒与其他取向晶粒的关系。结果表明,{100}面近似平行板法线的柱状晶组织热轧及冷轧时都较稳定,难以发生再结晶,退火后晶粒尺寸粗大。热轧时的表面剪切力和反复冷轧及退火会逐渐减弱这类组织及织构;退火次数越多,消除的效果越好。本文讨论了这类织构在电工钢中的作用及对磁性能的影响。
X-ray diffraction and EBSD orientation imaging were used to investigate the microstructure and texture evolution of the initial columnar grain structure during hot rolling, cold rolling and annealing. The effects of cubic orientation, rotating cubic orientation grains and other oriented grains Relationship. The results show that the {100} plane parallel to the normal of the columnar crystalline structure of both hot and cold rolling are more stable, difficult to recrystallize, coarse grain size after annealing. Surface shear stress during hot rolling and repeated cold rolling and annealing will gradually weaken this type of organization and texture; the more annealing times, the better the elimination effect. This paper discusses the role of such textures in electrical steel and its effect on magnetic properties.
