Abstract
X-ray diffraction analysis with synchrotron radiation and scanning electron microscopy are used to perform a complex study of the structural and phase states of a hydrogenated palladium-based membrane alloy. Fluctuations of the phase composition of alloy are considered after the introduction of hydrogen into the metallic system. Areas of the hydride (β) phase and diluted hydrogen solid solution (α phase) are found in the alloy. The processes that take place in the crystal lattice in the course of the β ↔ α transformation are determined. The development of defects and changes in the root-mean square displacements of alloy atoms, which result from the reaction of a material with occluded hydrogen, are analyzed.
