The regularities of formation of composite materials from CuAl9Mn2 bronze and 9MnSi5 steel by wire-feed electron beam additive manufacturing are reported. It is shown that an introduction of the strengthening phases of a material with a higher melting point (9MnSi5) into the material with a lower melting point (CuAl9Mn2) results in the formation of strengthening phases with dendritic structure uniformly distributed in the material volume. In the cases where a material with a higher melting point (9MnSi5) is fed into the material with a lower melting point (CuAl9Mn2), an inhomogeneous structure is formed, containing a number of defects of various shapes and sizes. The mechanical properties of the samples of the first type are characterized by an increased strength and plasticity compared to the base metal. The structure of the samples of the second type contains numerous defects, which in some cases sharply deteriorates their mechanical properties. The chemical composition of the sample components and their distributions in the samples vary from layer to layer.
