摘　　要：对由成品取向硅钢片经对称和非对称轧制获得的薄带进行普通与磁场退火,考察了磁场及非对称轧制对取向硅钢薄带初次再结晶织构的影响·发现磁场退火显著增加对称轧制薄带的再结晶Goss织构组分,减少非对称轧制薄带的Goss织构组分;非对称轧制在普通退火时增加Goss织构组分,而在磁场退火时使之明显减少·磁场的作用可以通过磁晶各向异性能和磁有序对晶界迁移的影响来解释·The commercial grain-oriented silicon steel was reduced to thin strips via symmetric and asymmetric cold rolling, which were annealed with and without magnetic field. The effects of magnetic field and asymmetric rolling on primary recrystallization textures were investigated. It was found that magnetic annealing can significantly increase Goss texture component ({110}〈100〉) in symmetrically rolled thin strip but decrease it in asymmetrically rolled thin strip. On the other hand, asymmetric rolling can increase Goss component after ordinary annealing but decrease it obviously after magnetic annealing. The effect of magnetic field on recrystallization texture can be explained in terms of the change in grain boundary migration caused by magnetocrystalline anisotropy energy and magnetic ordering.
