Аннотация: The object examined is the composite material 20-steel M1-copper L80-brass obtained by explosion welding. It is shown that as a result of mechanochemical interaction during explosion welding in a layered composite material in contact zones, reaction products are formed in the form of nonequilibrium and equilibrium phases, including the nonequilibrium electronic phase of Cu₅Zn₈ in brass-L80 and the non-equilibrium у-iron phase. It is shown that the structural transformations in the contact zone of the layers of the composite material are the result of an abnormally rapid mass transfer of copper to iron and zinc from brass to copper, as well as the fact that mechanochemical processes occur in the wave mode. The microhardness of the layers of the obtained composite material was studied.
