The developed dislocation structure that forms during cryorolling of a D16 alloy is found to be retained after short-term heating to 200°C. At higher temperatures, it undergoes recovery and recrystallization with the formation and growth of nanograins. Rolling intensify the decomposition of a preliminarily supersaturated aluminum solid solution, proving the alloy high-strength after artificial aging at a lower temperature and a shorter time as compared to a conventional T6 temper.
