摘　　要：采用光学电子显微镜和ODF分析方法,研究了两种CSP工艺生产的无取向电工钢组织和织构类型对磁性能的影响。结果表明:随着钢中(Si+Al)含量增加,晶粒尺寸增大,铁损降低;当{100}<0vw>和α、η纤维织构组分增加后,电工钢磁性能得到改善;随着{111}<112>织构组分强度降低,磁感明显提高。The distribution and composition of the texture and microstructure in two different the low grade cold rolled non- oriented silicon steel have been investigated using optical microscope and X - ray diffraction ODF analysis methods. The influences of texture types and microstructure on the magnetic properties are discussed. The result shows ：as the content of （Si ＋ Al） increase, grain size is bigger and iron loss is reduced; with increasing of orientation in density of the {100} 〈 0vw 〉 and α or η fiber texture, magnetic properties is increased, and the intensity of { 111} 〈 112 〉 component decreasing causes magnetic flux increasing obviously.
