Isochronal annealing at 120 to 460K was applied to ordered and disordered samples which had been bombarded, at temperatures below 85K, with protons, a particles and C ions with energies of 4 to 42MeV. In ordered samples, 2 large recovery stages centered around 290 and 380K were observed. In disordered samples, a small stage centered around 150K and 3 large stages centered around 190, 280 and 380K were observed. In both ordered and disordered samples the 280 to 290K, and 380K, stages were attributed to the migration of free vacancies and the associated long-range ordering, and to the migration of vacancies liberated from vacancy clusters and the associated ordering, respectively. The 150 and 190K stages in disordered samples were attributed to the migration of Cu and Au interstitials, respectively.
