The stage I recovery (below 60 °K) of deformed 99.999% purity Pt has been investigated by residual electrical resistivity measurements. After extensions of 1 to 3% at 5 °K, recovery peaks were observed at (16 ± 1), (28 ± 1), and (36 ± 1) °K, with associated activation energies (0.05 ± 0.01), (0.073 ± 0.01), and (0.14 ± 0.01) eV. A prior deformation and 300 °K anneal not only increased the stage I recovery by a factor of two, but also enhanced its structure. The 16 °K substage was due to short range defect migration. The 28 °K substage was similar to that observed after electron irradiation of Pt, which is attributed to free interstitial migration. The main Frenkel pair annealing substages which are observed after fast particle irradiation were absent in deformed Pt.
