摘要： A method for producing a motor vehicle component from a 6000 series aluminum alloy including providing a blank made of a 6000 series aluminum alloy, rapid heating of the blank to a temperature between 450 deg. C. and 600 deg. C. at a heating rate of more than 15 K/s in a period of less than 20 seconds, ending the heating process and optionally homogenizing, if a grain size between 20 and 50 μm has been produced, quenching the blank thus tempered, applying a lubricant, preferably at 20 deg. C. to 100 deg. C., forming the cooled blank in a forming tool, wherein the time between completion of the heating process and the start of the forming is less than 30 seconds, and aging.

摘要： A tool for hot forming and press hardening a steel structure includes an upper tool and a lower tool, each having a base body made of highly heat conductive material and comprised of at least two segments. The base body of at least one of the upper and lower tools has a cooling channel. Arranged on the base body of at least one of the upper and lower tools is a wear protection shield.

摘要： A method for producing a motor vehicle component includes the steps of providing a precipitation-hardenable blank composed of a 6000 or 7000 grade aluminum alloy, solution-annealing the blank at a temperature between 350° C. and 550° C. for a time period of 2 to 30 min., in particular 3 to 20 min. and preferably 5 to 15 min., in particular at a temperature between 440° C. and 480° C. in the case of a 7000 grade aluminum alloy, and in particular at a temperature between 490° C. and 545° C. in the case of a 6000 grade aluminum alloy, subjecting the solution-annealed blank to partially different quenching, a first region being quenched to a temperature between 150° C. and 250° C., and a further region being quenched to a temperature below 150° C., deforming the blank during or after the partially different quenching.
