    摘要: [PROBLEMS] To provide a method for refining the texture of a surface layer part in a ferrous material, to provide a ferrous material having a microscopic texture which can realize improved properties and prolonged service life of cutting tools, blades, and the like, and to provide a blade with a cutting edge formed by fabricating a microscopic texture region, wherein the expression "refining a texture" means the refinement of base metal crystal grains and the refinement of carbides.
    [MEANS FOR SOLVING PROBLEMS] A method for refining the texture of a ferrous material, comprising a first step of forming a carbide refined region and a second step of forming a texture refined region. In the first step, the surface layer part in the ferrous material is locally and rapidly heated by a laser beam to form a melt reservoir which is then rapidly solidified to form a carbide refined region. In the second step, the carbide refined region formed in the first step is subjected to a friction agitation process to form a texture refined region.
