The effects of tensile stress and strain on magnetization and magnetic domains in silicon steel sheets were investigated. The magnetization of elastic deformation regions decreased with increase of strain and the strain-magnetization properties of plastic deformation regions under stress showed peculiar characteristics. The magnetization increased with decreasing strain. We observed Lancet and other domains in a sample, especially around the boundary of crystal, after removing stress applied to a plastic deformation region. This phenomenon can be explained by changes in the domain structures, which were partly observed. This results obtained in this investigation can be applied to the nondestructive detection of fatigue in metallic magnetic materials.

The effects of tensile stress and strain on magnetization and magnetic domains in grain-oriented silicon steel sheets were investigated. The strain-magnetization properties of plastic deformation regions under stress showed peculiar characteristics. The magnetization increased with decreasing strain and, after reaching a peak value, decreased with decreasing strain. We observed Lancet domains in a sample after removing stress applied to a plastic deformation region. This phenomenon can be explained by changes in the domain structures, which were partly observed. The results obtained in this investigation can be applied to the nondestructive detection of fatigue in metallic magnetic materials.
