Abstract:
The development of macroscopic inhomogeneities in in the form of Chernov–Luders bands and jump-like deformation bands (Portevin–Le Chatelier effect) in plastic metal flow is studied. For these two cases, regularities in the development of deformation inhomogeneity were established, and the kinetics of motion of the fronts of Chernov–Luders bands and jump-like deformation bands was studied. It is shown that the Chernov–Luders fronts and the jump-like Portevin–Le Chatelier deformation can be considered, respectively, as macroscopic self-oscillatory processes of switching and excitation in deformable media of different nature.
Keywords:
plasticity, deformation, localization, deformation bands, metal structure, defects, dislocations.
