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 Is 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.
