Theoretical studies of feasible rotations of the crystal lattice during the deformation of samples with an FCC structure under uniaxial tension are carried out. The results of the experimental determination of the magnitudes of these rotations for various grains of two–dimensional polycrystalline aluminum samples after their deformation by the same strain value are presented. For the first time, it has been theoretically shown and experimentally confirmed that under uniaxial tension of a specimen under the conditions of operation of only one slip system, regardless of the scheme of rotation, the magnitude of the rotation is determined only by the angle between the direction of the tensile axis and the slip direction before deformation of the specimen.
