METHOD FOR MANUFACTURING A MOTOR VEHICLE PART MADE FROM A HARDENABLE ALUMINIUM ALLOY |
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. |
