| 摘要 |
The invention relates to a method for producing a metal component having at least two regions of differing strength properties within said component, obtained by differing cooling speeds of the different regions, characterized by the following method features: a metallic base body (1), which has at least austenitizing temperature, is provided, a region of the base body (1) is shielded during subsequent heat treatment of the base body (1) until the component temperature of said region has dropped to a predetermined temperature (T2) below the austenitizing temperature, but still above martensite start temperature, wherein an average cooling speed below the cooling speed which is critical for martensite formation prevails in said component region, while the unshielded region is kept to at least the austenitizing temperature, the shielding (3) is removed, the base body (1), having a graded temperature profile, is subjected to a reshaping process by a tool, wherein a cooling speed above that which is critical for martensite formation prevails at least in the previously unshielded region. A device for carrying out the method according to the invention has a shielding device (3) having one or a plurality of contoured cover elements (4) for shielding a predetermined region of a base body (1), preferably of a circuit board, wherein the shielding device (3) is designed to stay in the heating unit (2, 5) during tempering of the base body (1) before reshaping the base body in the reshaping tool. |
