Abstract
The invention relates to a method for hardening a sheet or strip made of an aluminum alloy of the 6xxx row and to a sheet or strip produced using said method. In order to accelerate the hardening method, a multistage thermal treatment is proposed which includes a process of maintaining a second holding temperature (T2) ranging from 150 to 250° C. for a second holding time (h2) and a subsequent second accelerated cooling process, wherein the second holding process together with the subsequent second accelerated cooling process interrupts the first holding process multiple times, thereby dividing the first holding process into holding stages, in each case at a first holding temperature (TI) ranging from 60 to 140° C. and for a first holding time interval (hIa, hIb, hIc, hId, hIe) which lasts longer than the second holding time (h2).
