The influence of strain rate in the range of 10^โ€“1^ to 10^โ€“5^ s^โ€“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.
