Abstract
Alteration in the deformation structure of copper single crystals and the Hadfield steel polycrystalline in the cross section depend on the distance from the friction surface. The following sequence of substructure formation has been determined: a mixing zone with nanograins and nanotwins, a fragmented substructure with microbands, microtwins, a cellular and tangled substructures, and a substructure with chaotic dislocation distribution. Hadfield steel has a much greater number of nanotwins in the surface layer than copper and it has a layer of microtwins. Evolution of dislocation structure when approaching the friction area was found to be similar to the evolution of substructures under active plastic deformation.
