摘要：
Special features of plastic deformation on the yield plateau and in the linear and power-law stages of tension of specimens of steel 09G2S are studied using the methods of correlation of digital images, surface topography, scanning and transmission electron microscopy. It is shown that a Chernov–Luders band consists of six alternating bands of localized strain growing from germinative centers. The periodically arranged germinative centers near the edges of the specimen form around dipole maximums, i.e., maximums of the longitudinal standing elastic wave. Each band of localized strain is represented by a set of parallel mesobands differing in their width, orientation and developed substructure.
