Аннотация:The Pd–5.3 at % In–0.5 at % Ru foil subjected to electrolytic hydrogenation and subsequent prolonged relaxation (for 55 000 h) has been studied by X-ray diffraction analysis. Diffraction reflections belonging to phases with different indium concentrations and palladium phases enriched in vacancies were found.
Phase transformations observed in the absence of hydrogen occur mainly at the expense of vacancy migration; the vacancies are formed during hydrogenation and remain in vacancy complexes and alloy matrix up to the moment of the present study.
