<p><P>PROBLEM TO BE SOLVED: To provide a partial plastic working method for a component made of a high-hardness magnetic material which easily enables partial plastic working of the component made of the high-hardness magnetic material without deteriorating the original high hardness and magnetic properties in the surrounding area. <P>SOLUTION: When performing the partial plastic working on the components 4 and 12 made of the high-hardness magnetic material, parts 4a and 12b to be subjected to plastic working are heated and converted into a softened area A showing a hardness of≤HRC20 and a drawing degree of≥60%. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
