In the article was introduced the investigations defining optimization of the cryogenic processing after saturating the alloy AlCu4, 7. The qualification of the influence this processes was planned (in the function of temperature and time) on microstructure and the mechanical proprieties of this alloy. There are accept the wide range of the temperature 175oC - 350oC there made possible the settlement of the influence of the temperature of aging on the kinetics of the break-up of the permeated with solution [alpha] and then on the change of microstructure and mechanical proprieties. There were applied the times of aging from 30 to 240 min. Results of investigations were compared with results after such thermal processing itself without the cryogenic processing after saturating.
