The structural and phase transitions in the Al–Li–Cu–Mg–Zr–Sc–Zn alloy subjected to megaplastic torsional deformation under high pressure in the process of low-temperature annealing at 150°C have been studied by electron microscopy. It has been shown that the character of the nanocrystalline structure formed in the annealing process is determined by the specific features of the earlier existing deformation structure and demonstrates structural heredity. The effect produced by the structural state of the annealed alloy on the level of mechanical properties (hardness, plasticity, elasticity modulus, stiffness) is discussed.
