The potential of thermo-mechanical treatment, realizing the ef-fects of precipitation hardening and structural strengthening by severe plastic deformation, is analyzed for 1965–type high-strength aluminum alloy. The ability to achieve the unique alloy strength due to combination of nanostructurе of the matrix and high densities of nanodispersed phases of different origin has been shown. The nature of the alloy mechanical behavior resulted from structure and phase transformations under the treatment is discussed.
