Rules of dislocation sub-structure evolution in Al-Zn-Mg alloy subjected to compression and tension in various structural states were compared with the rules of deformation-relief formation. It was established that long aging of the alloy changed the deformation localization mechanisms, as compared with its evolution in alloy subjected to short-term aging.
