  • Patent number: 10378089
    Abstract: Methods for using a mold to partially harden semifinished products, which are comprised of hardenable steel and have at least partially an open-profile or closed-profile cross section, may involve a number of steps. For example, such methods may involve heating regions of a semifinished product above an AC1 temperature, positioning the semifinished producing in a mold, positioning an active mold cooling element adjacent to or in contact with the heated regions of the semifinished product, and cooling the regions of the semifinished product at a defined cooling rate so that a hardened microstructure in the cooled regions. These methods and corresponding devices provide low cost solutions that dispense with complete hardening of semifinished products and/or employing welded connections to provide various mechanical properties.

  • Patent number: 10118213
    Abstract: The invention relates to a method for the forming of a workpiece, in particular a blank, composed of sheet steel, in which method the following steps are performed in succession: providing a workpiece composed of multiple steel layers which have been non-detachably connected to one another by roll-bonding and of which at least two steel layers have a different strength and/or elongation at fracture, heating the workpiece, and subjecting the workpiece to hot forming. To ensure a high strength and at the same time the easiest possible formability, the invention proposes that at least one section of the hot-formed workpiece is hardened, and that the workpiece is subsequently subjected to cold forming in the region in which the hardening has been performed. The invention also relates to a corresponding workpiece.

  • Publication number: 20180272461
    Abstract: A steel workpiece may have an edge region and a core region. The object of specifying a steel workpiece wherein a maximum near-surface strength and nevertheless favorable surface properties are achieved, especially favorable scaling characteristics during hot rolling, is achieved in that the steel workpiece may be softer in the edge region than in the core region, and in that a sum total of alloy constituents C, Si, Mn, Cr, and N of the steel workpiece overall is greater than 1.45% by weight. And in some examples the sum total of the alloy constituents C, Si, Mn, Cr, and N of the steel workpiece is less than 4.5% by weight.

  • Publication number: 20180243863
    Abstract: A method for producing a component structure from a first component and a second component may involve connecting the first component to the second component by way of a thermal joining process. The component structure has good crash properties, has good vibration resistance, has a lightweight construction, and is produced cost-effectively at least in part because the first component being a steel composite structure comprising a softer layer and a more-rigid layer. The softer layer may have a lower material strength and a higher deformability than the more-rigid layer.
