Determining the Presence of Packing Defects in Palladium-Based Alloys by X-Ray Diffraction Method

The alloys studied in this work are of interest for the needs of hydrogen energy, electronics, pharmacology. The goal is to identify the regularities of the evolution of defect subsystems, which is necessary for the development of processes to improve the performance indicators of metallic systems. An analysis of the imperfections of the crystal lattice of the alloys Pd\({}_{93.5}\)In\({}_{6.0}\)Ru\({}_{0.5}\) (numerical indices—mass \(\%\)) and Pd\({}_{100-x}\)Pb\({}_{x}\) (\(x=5\), \(8\), \(12\), \(16\), \(20\) mass \(\%\)) was carried out based on the results of X-ray diffraction using synchrotron radiation (SR) from the Kurchatov Research Center. An assessment of the probability of the presence in palladium-based membrane alloys of two-dimensional defects of the crystal lattice, affecting the structure-sensitive properties of materials—packing defects (PD), was conducted. The dependence of the probability of PD formation on the concentration and type of the doping element in palladium has been established.
