<p>[PROBLEMS] A metal working method capable of continuously forming various metal elements that are increased in strength or ductility by micronizing a metallographic structure to thereby improve mass-productivity and reduce costs, and a metal element. When the deformation resistance of a metal element extending in one direction is locally lowered to form a low-deformation-resistance area that traverses the metal element and this low-deformation-resistance area is shear-deformed to micronize the metallographic structure of the metal element, a non-low-deformation-resistance area generating means is provided that increases deformation resistance lowered in the above low-deformation-resistance area to generate a non-low-deformation-resistance area, and a non-low-deformation-resistance area is generated along at least any one side edge of the low-deformation-resistance area by the non-low-deformation-resistance area generating means.</p> |
