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.

本文考虑了在塑性变形发展阶段出现的错位位错亚结构变化的动力学。详细研究了导致晶格变形的缺陷类型。获得了用于不同晶粒尺寸的合金中晶格畸变的定量参数。结果发现，错位的蜂窝网络和微孪晶子结构中的晶格弯曲和扭转参数取决于变形的程度。在微绞线附近和远离微绞线都研究了晶格畸变。结果表明，在不同的晶粒尺寸下，微孪晶的形成随着变形的增加而发生。
