摘要：

The paper considers the dynamics of changing of misoriented dislocation substructures appearing at a stage of developed plastic deformation. The types of defects, which induce the distortion of the crystal lattice are studied in detail. The quantitative parameters are obtained for the lattice distortion in alloys at a different grain size. It is found that the lattice bending and torsion parameters in the misoriented cellular-network and microtwin substructures depend on the degree of deformation. The lattice distortion is investigated both in the vicinity and far from the microtwins. It is shown that the microtwin formation occurs with increasing deformation at a different grain size.
