Cellular approximation of the method of the model electron density functional. Alloys of alkali metals

The expression obtained in Part 1 of this work for the total energy of a disordered binary substitution alloy is employed to calculate the thermodynamic characteristics of alloys of the systems Na-Rb, Na-Cs, Li-Na, Li-K, k-Rb, Rb-Cs, K-Cs, Na-K. A model expression, whose parameters are calculated starting from the equilibrium characteristics of the metals studied, is employed to describe the energy of interaction of ions with conduction electrons. In order to calculate the properties of alloys no additional parameters are introduced into the theory, but rather the values of the parameters of the pure components are employed.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 5, pp. 77–83, May, 1991.
