Cyclic hardening curves were documented. Dislocation structure was studied with the technique of oriented foils in TEM. SEM and AFM were used to investigate surface relief topography. The cyclic stress-strain response is characterized by initial hardening followed by the stabilized stress response. Surface persistent slip markings and slip bands lying along {111} planes in the interior of grains cut both channels and precipitates. Experimental results concerning the surface relief and dislocation structure are used to discuss the stress-strain response.
