On the mechanism of ordering of the solid solution of the Cu–Pd system according to the B2 type

Based on the results of studying the structure of the membrane foil using X-ray diffractometry, high-energy electron diffraction and high-resolution transmission electron microscopy, the temperature dependence of electrical resistance, hydrogen permeability, crystal-chemical criterion and the electronic structure of the components, the mechanism of ordering the Cu–Pd system according to the B2 type is substantiated.
