The mechanisms of severe plastic deformation are experimentally studied under alternating bending of high-purity aluminum polycrystalline foil attached to an elastically deformed flat specimen of commercial aluminum or titanium. New nonlinear wave processes associated with curvature solitons in surface layers of highly deformed metallic materials are revealed. We underline that it is necessary to account for the found regularities of severe plastic deformation in describing the behavior of solids under extreme loading conditions, of nanostructured materials, thin films and coatings.
