Abstract
The paper considers an inhomogeneous development of plastic strain at the Chernov–Luders band front in the bimetal consisting of carbon and austenitic steel layers. It is found that in the low carbon steel basal layer, the distribution of localized deformation at the yield point represents two zones similar to the Chernov–Luders band. In the austenitic steel coating layer, the distribution of localized deformation at the yield point represents two plastic wave fronts similar to the Portevin–Le Chatelier effect. The paper proposes a mechanism of nucleation of localized deformation bands in the frame of the model of the solid fracturing.
