“…The relaxation of diffusion filter-membranes took place at room temperature and external atmospheric pressure. X-ray diffraction studies were carried out using synchrotron radiation [6][7][8]. X-ray phase analysis showed that the crystal lattices of the samples have a face-centered cubic (FCC) unit cell for the main phase both before and after hydrogenation, and a small content of intermetallic inclusions enriched/depleted with yttrium [5][6][7][8].…”

Atomic force microscopy (АFМ) and high-precision scanning electron microscopy methods were used to study the surface of diffusion filter-membranes of alloy Pd93Y7. The formation of alterations in structure in one of membranes was established as a result from the homogenizing annealing at 900°C for 1 hours. It was found that the reversible doping of the membrane alloy with hydrogen caused the dispersion of the diffusion filter-membranes’ surface structure. Differences in changes by the surface structure are determined during the hydrogenation in directional and non-directional flow of hydrogen.

X-ray diffraction and high-precision scanning electron microscopy methods were used to study the long-term evolution of the defect structure of diffusion filter-membranes Pd-Y. Analysis of X-ray diffraction data and microelectronic photographs showed that the recovery of the dislocation structure in the membranes was not uniform. Differences in the processes of hydrogen conservation in the structure of membranes are determined reversible hydrogen doping. Preservation by alloy of superstructural ordered regions was detected.
