    • 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. Further, with respect to two non-low deformation resistance regions arranged to sandwich low deformation resistance region crossing the metal body, one non-low deformation resistance region is caused to have a relative position change to the other non-low deformation resistance region so as to effect shear deformation of the low deformation resistance region. The low deformation resistance regions can be moved along the direction of drawing of the metal body.
    • 一种金属加工方法,其中金属体的微细结构细化,从而提高其强度,延展性或均匀性; 通过金属加工方法获得的金属体; 和通过金属加工方法得到的含金属陶瓷体。 在这种金属加工方法中,金属体或含金属陶瓷体(以下简称为“金属体”)的变形阻力局部地降低,从而在金属体中形成低变形阻力区域,并且低的剪切变形 实现变形阻力区域,以使金属体的微观结构细化。 特别地,金属体形成为单向拉伸构造,以便产生与金属体交叉的低变形阻力区域。 此外,对于与夹着与金属体交叉的低变形阻力区域配置的两个非低变形阻力区域,使一个非低变形阻力区域相对于另一非低变形阻力区域发生相对位置变化, 以实现低变形阻力区域的剪切变形。 低变形阻力区域可以沿着金属体的拉伸方向移动。
