Using the methods of x-ray diffraction and high-resolution scanning tunnelling microscopy, we revealed that the crystal-lites (crystal clusters) of the small size (??20–40 A) are main structural components in liquid and amorphous materials. The atomic agglomerations are located in volumes between clusters of liquid. They do not influence the formation of the diffrac-tion pattern, but influence only the intensity of scattering. It is possible only in the case when all distances between atoms are equiprobable that is typical only for gas. In amorphous ribbons, immediately after their fabrication by the melt spinning, the second structural component is absent. As a result, sufficiently large cavities are formed between clusters, and atoms of environment get there subsequently. If we can make this process controllable, we will obtain one more way of influence on structure, hence, on physicomechanical properties of materials in amorphous and nanocrystalline states.
