Kinetics of hardness changes of preliminary quenched and cryorolled at temperature of liquid nitrogen with a strain of e~2 alloy Д16 under further artificial aging in the temperature range of 100-190 oС has been analyzed. It is shown that the strengthening effect of cryodeformation can be kept and even slightly improved by subsequent low-temperature aging. Simultaneous operation of decomposition of aluminum solid solution and processes of recovery and continuous recrystallization of grain structure, which take place under annealing at T>150 oС, leads to the alloy hardness decrease up to the levels typical for non-deformed conventionally Т6 heat hardened state.
