Effect of Pb Small Additives on the Phase Composition and Microstructure Pd-Based Membrane Alloys

Abstract

The effect of Pb small additives on the microstructure and phase composition of palladium-based diffusion membrane-filters was studied in this work. In the present study, we comprehensively investigated the lead-containing palladium alloy by X-ray diffraction using synchrotron radiation and high-resolution scanning electron microscopy. The predisposition of the alloy to the formation of a conditionally homogeneous nanodisperse substructure with small values of micro-deformations is established. The stable preservation of the phase composition during a single hydrogenation is revealed.
