Polycrystalline copper and monocrystalline iron were tribomechanically loaded in a defined way. By fundamentals of a continuum mechanical analysis of the stress field and a transmission electron microscopical investigation of the dislocation arrangement conclusions were made regarding the crack nucleation, the crack propagation and the wear resistance. The proved development of a dislocation cell structure is an adaptation of the material to the friction loading to tolerate a high number of loading cycles without wear.
