Magnetostrictive properties of cube-textured Si-steel sheets by oxide-separator-induced decarburization

摘要

The advantages of cube texture, {100}<001>, in electrical steel sheets have been recognized for the last half-century. Yet, no commercial electrical steel possesses this texture. Technical difficulties in developing the cube-texture in Si-steel sheets as well as drawbacks in the magnetic properties for the previous cube-textured materials throw obstacles in the development of strips of this kind. It has been reported that the previous cube-textured Si-steel sheet with a coarse grain structure (25mm in diameter) is largely magnetostrictive (over 10{sup}(-5)).
