摘要:
The invention relates to a method for producing partially hardened steel components in which a blank is subjected to a temperature increase that is sufficient for a quench-hardening and after reaching a desired temperature, the blank is transferred to a forming tool in which the blank is quench-hardened or the blank is cold-formed and the component obtained by the cold-forming is then subjected to a temperature increase. During the heating of the blank or component, absorption masses rest against and/or are spaced with a small gap apart from regions that are intended to have a lower hardness and/or higher ductility; with regard to its expansion and thickness, its thermal conductivity, and its thermal capacity and/or with regard to its emissivity, the absorption mass is dimensioned so that the thermal energy acting on the component in the region to remain ductile flows through the component into the absorption mass.
