Electron microscopy studies were conducted for the fine structure of ion-doped layer on 30ChGSN2A steel obtained by ion implantation of monotectic tin-doped copper–lead alloy Cu64Pb36[Formula: see text]Sn. Formation of a multi-level hierarchical structure was detected. The features of formation of each layer were analyzed, and it was found that the main mechanism of formation of these structures is diffusion and relaxation resulting in the occurrence of internal stresses both in the surface layer and in the sheet of 30ChGSN2A steel. Relaxation of elastic stress fields results in translational–rotational deformation forming various vortex structures.
