摘要(Abstract)：

将含Cu高硅钢薄板退火后,以不同方式冷却,通过微观组织观察、织构分析以及磁性能测量,研究了冷却速度对含Cu高硅钢再结晶组织、织构及磁性能的影响。结果表明,冷却速度对再结晶组织几乎没有影响,但冷却速度减慢会提高{100}面织构的含量,降低{110}和{111}面织构的含量;0.4Cu试样的晶粒尺寸略大于0.2Cu试样,不同Cu含量试样织构组分差异不大;冷却速度和Cu含量共同作用下,冷却速度对高硅钢磁性能的影响占主导因素。冷却速度越慢,织构因子越大,磁感越高,{100}面织构含量越高,残余应力越小,并且高硅钢中长程有序度越高,有序相的反相畴尺寸越大,这些因素都有利于降低铁损。
