It was pointed out that studies of alloys, which exhibited short-range, long-range or negative short-range order, had shown that almost all radiation damage (correlated and non-correlated Frenkel defects) was made up of <110>-replacement collision sequences. That is, of dynamic <110>-crowdion propagation. In many of the above materials, static <110>-crowdions were stable; most of them as <110>-crowdion-vacancy pairs. The original degree of long-range order, for instance, was obtained when <110>-crowdion-vacancy pairs were annihilated in recovery sub-stage ID. During further annealing, an increase in the degree of order was observed in the temperature ranges of recovery stages III and IV, respectively. These increases were caused by migrating <100>-split interstitials and vacancies, respectively, which were annihilated in the respective recovery stages. The activation energies for migration of these defects were determined for many alloys, and it was found that these energies varied only very slightly - with increasing concentrations of component atoms - with respect to the values which were obtained for pure materials. The activation energies for the migration of <100>-split interstitials and vacancies were determined for many alloys, and the values which were obtained agreed with those measured during annealing following low-temperature irradiation.
