Evolution of the fine structure of Pd–5.3 at % Ιn–0.5 at % Ru solid solution after hydrogenation

Abstract

Fine-structure parameters, such as the effective coherent domain size D_hkl and microstrain ε_hkl, of Ρd–5.3 at % Ιn–0.5 at % Ru alloy foil, which was subjected to electrolytic hydrogenation and subsequent prolonged (for 55000 h) relaxation, have been determined using X-ray diffraction data. The hydrogenation and subsequent relaxation of the alloy have been found to result in the refinement of coherent domains CD(hkl) and increase in the microstrains ε_hkl.
