Abstract: The present invention provides a method for processing a metal body which can turn a metal structure of the metal body into a finer grain structure thus obtaining the high strength and the high ductility. In a method or an apparatus for processing a metal body which turns the metal structure of the metal body into the finer grain structure by forming a low deformation resistance region where the deformation resistance is locally lowered in the metal body and by deforming the low deformation resistance region by shearing, using a non-low deformation resistance region forming means which forms a non-low deformation resistance region by increasing the deformation resistance which is lowered in the low deformation resistance region, the non-low deformation resistance region is formed along the low deformation resistance region.

Abstract: A method of working metal in which the microstructure of metal body is rendered fine to thereby enhance the strength, ductility or homogeneity thereof; a metal body obtained by the metal working method; and a metal-containing ceramic body obtained by the metal working method. In this metal working method, the deformation resistance of metal body or metal-containing ceramic body (hereinafter referred to simply as “metal body”) is lowered locally to thereby form low deformation resistance regions in the metal body, and shear deformation of the low deformation resistance regions is effected so as to fine the microstructure of metal body. In particular, the metal body is formed in unidirectionally drawn configuration so as to produce low deformation resistance regions crossing the metal body.

Abstract: The present invention provides a metal molding method, a metal molding machine and a metal molded body, wherein using a mold in which a molding space having a predetermined shape and a metal body lead-in space which is communicated with the molding space are formed, a metal body which is inserted into the metal body lead-in space is fed into the molding space by applying a predetermined pressure thus forming a molded product having a predetermined shape. Particularly, the metal body is deformed by shearing when the metal body is fed to the molding space from the metal body lead-in space thus turning the metal structure of the metal body into the finer grain structure.
