The elastic modulus recovery and the creep recovery of zone-refined copper specimens were examined after torsional deformation at -195℃. The isochronal annealings were performed over the temperature range from -155°to + 160℃. Two specimens, one annealed at 700℃ and the other at 250℃ prior to torsional deformation, showed distinct differences in their recovery behaviors. The role of dislocation rearrangements in the elastic modulus recovery was discussed for these two specimens. In the former, the pinning of dislocations by point defects may be a main mechanism, while in the latter dislocation rearrangements seem to play an important role.
