Abstract (en)
[origin: WO2010066896A1] The invention relates to a process for producing a component having improved elongation at break properties, in which a component (6) is firstly produced, preferably in a hot forming or press curing process (4), and the component (6) is heat treated after hot forming and/or press curing (4), where the heat treatment temperature T and the heat treatment time t essentially fulfill the numerical relationship T = 900·t-0.087, where the heat treatment temperature T is in °C and the heat treatment time t is in seconds. The invention also relates to a component, in particular an automobile body work component or the chassis of a motor vehicle, which has been produced by such a process. The invention further relates to the use of such a component as part of an automobile body or a chassis of a motor vehicle.
