Summary:The article discusses computer modeling of the stage of hot stamping of the volumetric thermal and stress-strain state for a product - a resistance welding electrode using the specialized professional program Deform 3D. Computer modeling has established that the greatest influence on the hardness over the cross section of the manufactured electrode is exerted by: average normal stress, intensity of deformation and deformation rate, which contributes to the generation of a large number of dislocations. The features of the formation of the macro- and microstructure of the Cu-MMNCr composite material were studied under the conditions of a combined process of casting and stamping with subsequent heat treatment. The mechanism for identifying grain boundaries is described. The relationships between the distribution of hardness and the parameters of the thermal and stress-strain state in the volume of a product made of the Cu-MMNCr composite material using the combined method of casting and stamping with subsequent heat treatment have been derived. The results of the physical and mechanical properties of the Cu-MMNCr composite material obtained by a combined method of casting and stamping with subsequent heat treatment are presented.
