Some possibilities of studying real microscopic structures by X-ray kinetic techniques are considered. Taking variable-composition Pd-W alloys as examples, a comparative time dependence analysis of the X-ray diffraction pattern (i.e., of the intensity and width of diffraction maxima) is carried out for palladium-metal alloys relaxing after hydrogen saturation. It is shown that the dependences are of nonmonotonic — at some relaxation stages, of oscillatory — character. Analysis indicates that these dependences are due to the self-organisation effect operating during the diffusion evolution of an alloy structure having submicroscopic heterogeneity. The self-organisation mechanisms most likely for a system of local short-range order regions, hydrogen-containing clusters, defects, and hydrogen atoms are considered. Classes of materials allowing such phenomena are discussed.
