摘　　要：研究了复合稀土微合金化对高牌号无取向硅钢磁性能的影响,借助EBSD、XRD、交流磁性测量仪对实验钢的组织、织构以及磁性能进行了分析。结果表明:复合稀土微合金化可适当减小高牌号无取向硅钢的晶粒尺寸,增强其理想{100}面织构组分,减弱其有害{111}面织构组分。实验钢的铁芯损耗P15/50由3.09 W/kg降低到2.73 W/kg,磁感应强度B50由1.689 T增加到1.739 T,磁性能提高。The effects of mischmetal micro-alloying on the magnetic properties of high grade non-oriented silicon steels were studied. The microstructure, texture and magnetic properties of the tested steels were analyzed by EBSD, XRD and instrument for AC magnetic measurement. The results show that mischmetal micro-alloying can refine the grains of the tested steels, enhance their { 100} surface texture and reduce their { 111 } surface texture. The iron loss P15/50 of the experiment steels reduces from 3.09 W/kg to 2.73 W/kg and the magnetic flux density B50 enhances from 1.689 T to 1.739 T, so the electromagnetic performance improves.
