“…The degree of local ordering in such liquid systems can be studied by estimating Warren-Cowley short range order parameter (α 1 ) with the knowledge of (S CC (0)) [16,17]. The expression for α 1 in terms of S CC (0) is given as…”

“…At first, the viscosities of the component metals at the temperature of investigation are computed from Eq. (17) with the aid of the values of constants η 0i and E which are taken from the reference [30]. The comparative study of the viscosity of the liquid alloy is then done by computing the viscosity from Eqs.…”

“…Thus enormous work has been done by several theoreticians leading to the development of different theoretical models [5][6][7][8][9][10][11][12][13][14][15][16] for the investigations of the thermodynamic and microscopic structural behaviour of liquid binary alloys. This work is focused on the study of the thermodynamic and microscopic structural behaviour of Pb-Tl liquid alloy at 773 K on the basis of regular associated solution model [17][18][19][20][21].…”

Thermodynamic properties, such as free energy of mixing, heat of mixing, entropy of mixing, activities and the microscopic structural properties, such as concentration fluctuation in long-wavelength limit and chemical short-range order parameter of Pb-Tl liquid alloy at 773 K have been studied on the basis of regular associated solution model. We have estimated the mole fractions of the complex and the unassociated atoms assuming the existence of complex as energetically favoured in the liquid state. The compositional contributions of the heat of mixing of the species Pb and Tl and the heat of formation of the compound to the net enthalpy change have also been studied. The transport properties such as, viscosity and the ratio of mutual and intrinsic coefficients have been studied using different approaches. The surface concentration of Tl atoms has been computed and it has been employed to calculate the surface tension of Pb-Tl liquid alloy. Both the theoretical and the experimental values of the concentration fluctuation in long-wavelength limit are found to be less than the ideal value, revealing that the concerned system is hetero-coordinating in nature. The interaction energies are found to be temperature dependent and respective alloy is found to be weakly interacting system. BIBECHANA 13 (2016) 100-113

“…In this paper, we have used two different models for the study of the properties of two Cd-based molten alloys. The liquid Cd-Hg alloy at 600 K has been studied by using regular associated solution model [13][14][15][16] and the liquid Cd-Na alloy at 673 K has been studied by using quasi-chemical expression [17,18] for weakly interaction systems.…”

“…We have assumed Cd 2 Hg complex in molten Cd-Hg alloy and Cd 2 Na complex in Cd-Na alloy for the study. In case of regular associated solution model the equations for thermodynamic and microscopic functions are derived by treating the binary solution as a ternary mixture of complexes and unassociated species [13][14][15][16], whereas in case of quasi-chemical expression the equations for these functions are derived by assuming grand partition functions for the clusters of two lattice sites [17]. In both models the interaction energy parameters are assumed to be temperature dependent.…”
