The results of optical and electron microscopic metallographic studies and energy-dispersive analysis of the structure and composition in the zone of connection of copper M3 with steel 30 CrMnSiA after explosion welding, subsequent quenching from a temperature of 880 ° C and high tempering at a temperature of 520 ° C are presented. The change in the distribution of hardness and chemical elements over the cross section of the bimetal, the formation of martensite in melts after quenching and its decomposition during high tempering are shown.
