The structure of polymetallic materials samples obtained by friction stir processing of a sheet package made from AMg5 aluminum alloy and L63 copper alloy is studied. The regularities of structure formation at the deformation-initiated stirring of system components in comparison with the similar process at sample production from homogeneous materials are determined. The localization of the main defective zones in the samples during coatings formation is studied. Intensive diffusion and mechanical mixing of system components, leading to the formation of a large number of different phases in the “coating-substrate” system, has been revealed.
