Résumé

The internal friction and elastic modulus of high purity magnesium were studied during irradiation at 2 K with 0.4 - 0.6 MeV electrons and subsequent anneal sequences. The sallent feature of the results is the evidence of a marked pinning stage in the temperature interval 9 to 13 K. This indicates that long-range diffusion of elementary interstitial defects occurs at these temperatures. Post-irradiation anneals enabled also the discovery of two relaxation peaks centered at 6 K and 15 K, respectively. These stem from the arrival of the diffusing self-interstitials at dislocations, and presumably from their interactions with geometrical kinks.
