The influence of strain rate in the range of 10^–1^ to 10^–5^ s^–1^ on the compression behavior of a cryomilled 5083 Al alloy is studied. The compression flow stress remains constant after an initial short strain hardening and a small stress dip, which indicates a dynamic saturation of dislocations.
