Impact of long-term relaxation on the phase composition of Pd–5.3 at % In–0.5 at % Ru alloy after hydrogenation
The structural state of a hydrogenated foil of Pd 5.3 at %–In 0.5 at % Ru alloy with a long relaxation time (55000 h) is studied via X-ray diffraction. Changes in the phase composition of the alloy during relaxation after hydrogen escapes from it are established. The quasi-stability of the distribution of the widths of areas of coherent scattering (ACS) is revealed by the concentration of indium atoms in directions ≪100≫ and ≪111≫.
