The aim of this study was to reveal of fundamental contribution for the transfer ot the retrogression and reaging treatment. For the production of formed components from the high-strength aluminum alloy EN AW-7020 using the retrogression and reaging treatment (RRA). The transferability to an overall production chain with integration of the forming process into the course of RRA treatment is discussed and acquired a recommendation. For this purpose, the mechanical material behavior as well as the corrosion behavior are characterized according to the respective process steps in order to elaborate an overall process window in the examined limits for temperature and time during the RRA treatment.
