【 摘 要 】

A complex technique of theoretical and experimental research of the process of manufacturing bimetallic tubular elements by drawing with thinning of a two-layer billet of dissimilar metals using the relief of the boundary surface is presented. Using the theory of plastic flow, a mathematical model was developed for the deformation of the joint drawing process with thinning of two dissimilar metals with heating under conditions of a plane deformed state, which allowed to establish the relationship between the parameters of the stress-strain state on the boundary surface and the degree of deformation of the thinning with the original geometric parameters of the workpiece to fill the relief of the boundary surface
