In the article, by changing the technological modes of strip rolling in helical rolls and a longitudinal wedge mill, the phase and structural transformations in the foil blank are studied. It was found that rolling in helical rolls with twelve passes of the initial alloy billet 2017 provides its nanostructuring with the formation of a mixed structure. It is shown that rolling alloy 2017 in helical rolls leads to an increase in the density of dislocations. It has been proved that with an increase in the number of passes, the excess phases, mainly of coarse particles of the (CuFeMn) 3Si2Al15 phase, are significantly crushed. The volume fraction of these particles does not change.
