Solid-phase synthesis by joint plastic deformation of the components under high pressure opens up completely new possibilities in creating new materials. A key step in the materials synthesis during severe plastic deformation (SPD) is the delivery of atoms of different components to specific locations in the sample. It is carried out due to the mixing process in the solid phase. The details of the process are still largely unexplained in microstructural terms. This hinders the employment of the enormous potential of SPD synthesis. The report presents the results of studies on a mixing of metals during the formation of nanostructured metal compositions by SPD technique.
