PROBLEM TO BE SOLVED: To provide a method of locally reforming a member for working such as a magnesium alloy plate, to provide a member subjected to the reforming, to provide a method of forming the member for working, to provide a formed body obtained by utilizing the forming method, and to provide a production method therefor. SOLUTION: A rotary tool 10 is rotated, and the tip thereof is inserted into a member 50 (such as a magnesium alloy plate) for working. In this state, while softening the member 50, the rotary tool 10 is moved along a prescribed pathway L. The movement path L is set inside the face of the planar member 50. The member 50 for working subjected to the rotary tool treatment is heat-treated, e.g., in a temperature range of 100 to 250°C. In this way, the member 50 having a region locally reformed along the path L along which the rotary tool 10 is moved is obtained. The reformed member 50 is, e.g., suitable for such a use where the part including the reformed region is bent. COPYRIGHT: (C)2004,JPO
