“…The compound formation (CF) model is based on the assumption that the constituent atoms, A and B of a binary alloy, A-B preferentially arrange [3,5,11,14,17] to form chemical complexes, compounds, pseudomolecules, A μ B ν in the melt, i.e. :…”

“…In order to understand the energetics of strong interacting binary liquid alloys, various theoretical models [1][2][3][4][5][6], based on the formation of intermetallic compounds, pseudomolecules, complexes in the melt, are used. The associative tendency between unlike atoms of the alloy leading to compound formation (CF) depends [7] largely on interionic interactions and its intensities.…”

“…The computed pair potentials have been minimized [8,12] to obtain the hard sphere diameter of the component elements of the alloy. Besides, the concentration dependent thermodynamic and microscopic properties [3,[13][14][15] are greatly affected by the formation of intermetallic compounds in the melt. Without understanding the cause of anomaly in these properties, one cannot get the real picture of the mixing behaviour in such alloys.…”

“…It is also directly related to thermophysical properties such as chemical diffusion [26][27][28]. Once the Gibbs free energy of mixing, G M , of a liquid phase is known, S cc (0) can be expressed in terms of G M , or in terms of activity, a i as in equations (14) and (15).…”

The phase diagrams of Fe-Pt and Ni-Pt liquid alloy systems show the existence of FePt and NiPt intermetallic compounds, respectively, in their solid intermediate states, and the associative tendency between unlike atoms in these liquid alloys has been analysed using the self-association model. The concentration dependences of mixing properties such as the free energy of mixing, G M ; the concentration fluctuations, S cc (0), in the long-wavelength limits; the chemical short-range order (CSRO) parameter, α 1 ; as well as the chemical diffusion, enthalpy and entropy of the mixing of Fe-Pt and Ni-Pt liquid alloys have been investigated to determine the nature of ordering in the liquid alloys. The results show that heterocoordination occurs in the alloys at all concentrations. The effect of CSRO on S cc (0), chemical diffusion, D, and the order parameter, α 1 , has been considered. The ordering phenomenon in the liquid alloys is also related to the effect of the atomic size mismatch volume on S cc (0).

Concept of complex formation model has been applied to account for the thermodynamic properties of liquid InNa alloy. The theoretical study reveals that the intermetallic compound In 3 Na 2 exists at stoichiometric composition. Our expressions reproduce successfully the asymmetric behaviour of free energy of mixing, enthalpy of mixing, s-type entropy of mixing, CSRO and phase separation in liquid InNa alloy. It is found that Na atoms segregate on the surface. The study reveals that various factors such as size difference and electronegative factor are not sufficient to account for the asymmetry in the system. The low value of order energy suggests that In-Na is a weak interacting system.
