INTERACTION BETWEEN POINT DEFECTS AND SN ATOMS IN NEUTRON IRRADIATED AL-SN ALLOY,

Abstract

The recovery spectrum of the extra-resistivity induced in pure Al by neutron irradiation at -195C is practically resolved in two recovery stages, conventionally indicated as stage In-2 and stage In-3, occurring in the temperature ranges -195C to -110C and -110C to 0C, respectively. The interpretation given for these stages is mainly based on the assumption that stage In-2 is due to the release and annealing of interstitials trapped at impurity atoms and that stage In-3 is due to the combination of mobile vacancy-type defects with immobile interstitial clusters formed during irradiation by the combination of single interstitials. New experimental evidence is given supporting the hypothesis that vacancy-type defects are mobile in stage In-3.
