Abstract

Electron microscopic observations, electrical resistivity, and lattice parameter measurements of annealed Pd-12.5 at. % Y alloy indicate the presence of long-range order in the form of a Pt7Cu superlattice. This is similar to the order found in Pd7Ce, which is also isomorphous with Pt7Cu. The order-disorder transformation temperature was found to be Tc = 783 ± 5 K. Evidence was found from resistivity measurements for the existence of an ordered structure in the hypostoichiometric alloys: Pd-10.0 at. % Y and Pd-8.0 at. % Y. The order-disorder transformation temperatures were lower than that for the stoichiometric alloy Pd7Y.
