20110011499 | METHOD AND DEVICE FOR HARDENING PROFILES - The invention relates to a method for producing hardened profiles, in particular hardened open profiles, wherein the component is at least partly heated to above the austenitizing temperature of the base material and after heating the component is cooled at a rate above the critical hardening rate, the energy necessary for the heating being introduced at least partly by induction, wherein free edges are provided in the component to adjust a temperature or hardness gradient over the cross section of the component, the size, type and extension of the edges being set for a desired degree of hardness and/or hardness gradient. | 01-20-2011 |
20110003113 | PROCESS FOR PRODUCING SHAPED COMPONENTS FROM HIGH-STRENGTH AND ULTRA HIGH-STRENGTH STEELS - This invention pertains to a process for producing shaped components from high-strength and ultra high-strength steels with tensile strengths >780 MPa, wherein a steel sheet-metal strip is fed to a roll-forming installation and in the roll-forming installation is passed through roll stands and deformed by means of deformation rollers acting on the steel sheet, and wherein to avoid hydrogen embrittlement in plastically deformed regions of the deformed steel sheet-metal strip compressive stresses are introduced by stamping and/or upset-forging and/or overbending and bending-back or by machining the strip edges. | 01-06-2011 |
