In the statistical theory of superlattices in binary alloys, the dependence of the interaction energy upon atomic arrangements is taken into account by regarding the interaction energy in Bethe's theory as an average quantity depending on the degree of order and the composition of the alloy. Two simple assumptions concerning the functional relationship of the interaction energy with order and composition are made. The first is a linear function of order and composition.

In the statistical theory of superlattices in binary alloys, the dependence of the interaction energy upon atomic arrangements is taken into account by regarding the interaction energy in Bethe's theory as an average quantity depending on the degree of order and the composition of the alloy. Two simple assumptions concerning the functional relationship of the interaction energy with order and composition are made. The first is a linear function of order and composition. The second is a linear function of the average numbers of pairs of atoms. The result of applying these assumptions to superlattices of the type AB is that the critical temperature as a function of the composition is a maximum for equal sumber of A and B atoms only when a certain relation between the coefficients in the assumed function is satisfied. In the cass of superlattices of type AB3 the theory of Bragg and Williams is used for simplicity. It is shown that when the composition varies, the maximum of the critical temperature may occur at any desired composition by a suitables adjustment of the coefficients in the assumed functions. There is thus a hope of removing the discrepancy between theory and experiment on this line. The anomalous specific heat at the critical temperature is also calculated for different compositions. In the case of the AB type of superlattices, Bethe's formula for the energy is no longer valid, and in order to calculate the specific heat, an approximate formula for the energy is obtained by analogy with the theory of Bragg and Williams. Finally, the problem of separation into more than one phase is briefly discussed.

The solubilities of potassium dichromate in mixtures of light and heavy water with various D_2O-contents hsve been measured at 25±0.03°. The solubility is expressed in two different ways: (1) S_n, the number of moles of K_2Cr_2O_7 dissolving in 55.51 moles of H_2O-D_2O mixture with the mole fraction of D_2O equal to n; (2) S_x, the number of grams of K_2Cr_2O_7 dissolving in 1 gram of H_2O-D_2O mixture with the weight fraction of D_2O equal to x (see Table 1, pp. 321-322). The data are plotted in Fig. 1 (p. 323), and treated with the method of least squares, which yields the following empirical formulae: S_n = 0.5024 - 0.1467 n + 0.0174 n~2 S_x = 0.1478 - 0.0540 x + 0.0049 x~2 These formulae possess a mean deviation of ±0.18%, but the total experimental error is estimated to be about ±0.25%. From these formulae we obtain S_n~(D_2O)=0.3731; S_x~(D_2O)=0.0987. As D_2O, H_2O and K_2Cr_2O_7 constitute a three-component system, the composition of the liquid phase with K_2Cr_2O_7 saturated at 25°, expressed either in mole fractions or in weight fractions, is given in Table 2 (p. 324). The system represented by weight fractions is shown in Fig. 2 (p. 325). The above formulae permit an estimation of the solubility of potassium dichromate in HDO at 25°: S_n~(HDO)=0.4291 S_x~(HDO)=0.1208 In the present case of solubility phenomena, the substitution of deuterium for the second protium atom in the water molecule produces an effect only amounting to 76% of that caused by the substitution for the first protium atom. This agrees with previous observations on the density, the temperature of density maximum, the freezing point, the boiling point, the heat of fusion, the heat of vaporization, the vapor pressure, the viscosity, etc.
