Abstract:The stage I recovery (below 60 OK) of deformed 99. 999% purity Pt has been investigated by residual electrical resistivity measurements. After extensions of 1 to 3% at 5 OK, recovery peaks were observed at (16 f l), (28 & l), and (36 & 1) O K , with associated activation energies (0.05 f 0.01), (0.073 f 0.01), and (0.14 f 0.01) eV. A prior deformation and 300 O K anneal not only increased the stage I recovery by a factor of two, but also enhanced its structure. The 16 O K substage was due to short range defec… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
