Results of electron microscope studies of some binary and three-component alloys are analyzed. It is inferred that the chemical interatomic interactions in the alloys occur according to the principle of pair interaction. It is shown that a ternary alloy undergoes separation into diffusion pairs already in the liquid solution. When the temperature of the alloy decreases, particles of a new phase form inside each type of diffusion micropair. It is supposed that the high-entropy alloys, where diffusion micropairs cannot form due to decelerated diffusion of atoms, should not be suitable for industrial applications.
