Influence of Plastic Deformation and of Substitutional Gold on Defect Production and Recovery in Platinum

Abstract

Both the production of defects in Pt by deuteron irradiation at 6°K and the subsequent thermally activated recovery of these defects are perturbed when Pt is deformed or alloyed before irradiation. The atomic rearrangements that occur in the various recovery substages are known with perhaps less ambiguity in Pt than in any other metal. This knowledge is used to analyze in detail the interactions between the defects injected before the irradiation and the atoms displaced during the irradiation that produce these perturbations.
