Abstract

Some features of the magnetization reversal of Fe–3% Si sheet electrotechnical steel with different degrees of texturing have been studied. It was revealed that stripe samples, even with the very sharp edge texture {110}〈001〉 have a nonuniform magnetic permeability along the length of the stripe. It is established that this nonuniformity is due to the different sizes of crystallites and different orientations of their magnetization I_s with respect to the rolling direction of the studied samples. It is demonstrated that, to decrease the magnetic losses of anisotropic electrotechnical steel via the artificial reduction of its domain structure, it is reasonable to deposit locally strained zones not onto the entire sample surface but only onto areas with the maximum magnetic permeability.

线极化磁场中电工钢磁化反转的不均匀性

摘要

研究了不同织构程度的 Fe-3% Si 板电工钢的磁化反转的一些特征。结果表明，即使具有非常尖锐的边缘纹理 {110}<001>，条纹样品沿条纹长度也具有不均匀的磁导率。已确定这种不均匀性是由于微晶的不同尺寸和它们的磁化强度I _s相对于研究样品的轧制方向的不同取向。结果表明，为了通过人工减少磁畴结构来降低各向异性电工钢的磁损耗，将局部应变区沉积在不整个样品表面而是仅在具有最大磁导率的区域上是合理的。
