Abstract
Structural and phase transformations in commercial aging aluminum–lithium Al–1.2 Li–3.2 Cu–0.09 Zr–0.11 Sc–0.4 Ag–0.3 Mg alloy have been studied after severe plastic deformation by high-pressure torsion (at a pressure of 4 GPa with 1, 5, and 10 revolutions of the anvil) and natural aging (roomtemperature storage) for 1 week and 2 years. It has been found that, in this case, the process of static recrystallization is achieved in the alloy, the degree of which increases with an increasing degree of deformation and time of storage.
