The cyclic hardening curves and the cyclic stress-strain curves were measured and correlated with the change of dislocation substructure in grains and grain boundaries. In this study, an effort.was taken to explore: @1. the change of dislocation substructure as a function of the number of cycles; @2. the effect of the strain amplitude on the dislocation substructure in saturation; and @3. the role of grain boundary in the cyclic deformation.
