Using the pseudopotential method and the thermodynamic perturbation theory, the effect of pressure is studied on phase equilibria in binary alkali-metal alloys, which have different degrees of mutual solubility of the components. From the calculations, the K-Rb system is found to have a limited solubility of the components at low temperatures. The action of pressure on the K-Rb and Li-Na systems decreases the height of the immiscibility dome and increases the limits of the mutual solubilities of the components in the phase diagram. The hard-sphere model used to describe the kinetic properties of the melts describes well the temperature dependence of the self-diffusion coefficient and its variation with pressure.
