✦ Synopsis

Cyclic straining of annealed polycrystalline copper with constant plastic strain amplitudes results in initial hardening which is followed by long-term softening in the low amplitude region. The logarithmic softening rate was measured in dependence on the plastic strain amplitude, and the dislocation structures and the surface relief evolution were studied in order to explain the observed softening.
