description: Experimental results of the study of the effect of deformation and heat treatment on the physical and mechanical properties of nanostructured aluminum alloy D16 system Al-Cu-Mg are presented. The nanostructure of the material was obtained by high pressure torsion (HPT with specific pressure 6 GPA) at room temperature. There was constructed the kinetic dependences of specific electrical conductivity and microhardness on time of annealing and nature aging. It is shown that the potential increase in hardness and strength of nanostructured alloy D16 due to heat treatment (hardening + annealing; natural and artificial aging) can exceed the same characteristics for standard processing modes (T4 and T6) by 2-3 times. 
Using electron diffraction patterns was studied the effect of SPD (severe plastic deformation) on the formation of the nanostructure of the alloy D16 after 1 and 10 revolutions HPT: after 1 cycle, an ultrafine-grained (UFG) structure was formed with the presence of the high-angle misorientations and a grain size of ~ 160 nm; after 10 rotations there was obtained a nanostructure with a size of structural components of the order of 70 nm and predominantly high-angle misalignment. Also was calculated the interplanar distance of the point reflections in electron-diffraction patterns, the values of which correspond to the reference data of the compounds CuAlâ, Ð¡uâAlâ. The hardening phase CuAlâ indicates the passage of dynamic strain aging.
