Pure polycrysmlline aluminium specimens have been cyclically deformed at total strain amplitudes in the range 2 x 10 -4 to 1.4 x I0 -.~ at temperatures of 77 K, 163 K and 223 K. Transmission electron microscopy studies of dislocation configurations have been made. Wall structures including persisten
