要約(英語): The crystal grain shape of GO (Grain-Oriented steel) sheet is considered by two-dimensional polycrystal magnetic field analysis in which grains grown vertically and grains grown horizontally are compared. Because the grains grown vertically have more adjacent crystal grains in the direction of magnetic flux flow than the grains grown horizontally, they have uniform magnetic flux density distribution and then small iron loss. Therefore, the grains grown vertically are preferable to the grains grown horizontally in order to reduce the iron loss. Since this is the same conclusion as the three dimensional polycrystal model, it is said that the α angle of the crystal grain orientation angle is the main effect for the iron loss in consideration of the crystal grain shape.
