Original Abstract

Cyclic stress-strain response of UFG Cu under stress controlled loading changes qualitatively with the stress amplitude. For low stress amplitudes continuous cyclic hardening during the whole fatigue life can be seen. Nearly stable cyclic behaviour can be found for intermediate stress amplitudes and for high stress amplitudes pronounced cyclic softening is a characteristic feature. No detectable changes of microstructure were revealed by EBSD.
