Beschreibung
Zusammenfassung:	A method for producing a motor vehicle component is disclosed having the steps of providing a strain-hardened blank composed of a 5000 grade aluminum alloy, partially heating the blank in a first region to a temperature higher than 350° C., in particular to 400° C., the blank being kept at a temperature between 15° C. and 30° C., preferably at 20° C., in a second region, and the partial heating being performed in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, adjusting the temperature of the blank as a whole to between 150 and 350° C. in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, and deforming the blank to form the motor vehicle component in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, and cooling the motor vehicle component.
