    摘要: The present invention relates to a method for producing a hot-formed and press-hardened metal component for an automobile having at least two regions of different hardness. A hardenable sheet-metal blank is heated to at least an austenizing temperature and a first region of the sheet-metal blank is intermediately cooled at a cooling speed greater than the lower critical cooling speed of the material of the sheet-metal blank. The sheet-metal blank is then hot-formed and press-hardened in a press-hardening tool by quenching the first region from a bainitic structure transformation stage, thereby adjusting a mixed structure of martensite and bainite in the first region.

    摘要: In the method for producing from a metal strip peripherally contoured, elongated shaped blanks (6) having regions of different thickness along their length (L1), starting blanks (3) are first stamped from a metal strip having a constant thickness wherein the starting blanks are arranged at interleaved positions in the longitudinal direction of the metal strip. The starting blanks are subsequently guided separately through a rolling mill (5) with a longitudinal orientation and rolled in the rolling mill (5) into shaped blanks (6) having regions of different thickness.

    摘要: On a body structure (2) for an automobile (1) having a structural component (3) made of at least high-strength steel sheet, the structural component (3) is provided with a predetermined cutting location (5, 5a, 5b, 5c) for applying a separating tool. In the method for producing the structural component (3), a steel sheet is formed and subjected to heat treatment for forming regions with high strength and reduced strength. At least one region of the structural component (3, 7, 8, 12) with reduced strength is formed as a predetermined cutting location (5, 5a, 5b, 5c) for applying a separating tool during a hot-forming process of a steel sheet in a tool or during heat treatment of the structural component (3, 7, 8, 12) following a forming process in a tool by changing the mechanical properties.

    摘要: A transmission tunnel, in particular for installation in a motor vehicle body, is produced by hot-forming and press-hardening a sheet steel blank, and has a first region which underwent heat treatment, a second region which is not heat-treated, and a transition zone between the first and second regions. The transition zone is hereby defined by a width which is smaller than or equal to 50 mm. At least one component can be coupled to the transmission tunnel to form a floor assembly.
