“…This infers that Al-Cu alloys are compound forming over the whole composition range considered under this investigation. In addition to this the Warren-Cowley short range order parameter, α [17,18,26,[28][29][30] has been computed for Al-Cu alloys. α can be determined experimentally using S CC (k) and S NN (k) structure factors.…”

The Bhatia-Thornton (BT) correlation functions namely the number-number, concentration-concentration and number-concentration correlation functions in liquid binary melts are important parameters for understanding the complexities in binary liquids. In this paper, the microscopic BT correlation functions of liquid Al-Cu alloys are investigated using square well (SW) potential under mean spherical model approximation. These correlation functions are linearly related to the Ashcroft-Langreth type partial structure factors. Thermodynamically important microscopic function i.e. concentrationconcentration correlation function in the long-wavelength limit, S CC (0) is analytically calculated, which is well-known in BT formalism and is often used to characterized the mixing behavior in binary melts. The Warren-Cowley chemical short range order parameters, α as function of Cu concentration is also computed in the liquid Al-Cu alloys through structural studies in the long wavelength limit, which gives valuable information regarding ordering in melts. The compound forming behavior in Al-Cu alloys is evidenced by the results obtained for the value of S CC (0) and α . Further, transport properties in binary mixture have been determined by using BT-correlation functions and its long PAPER: Classical statistical mechanics, equilibrium and non-equilibrium

“…In 2010, the thermodynamic properties and microscopic structure of Cd-Na liquid alloys at 670 K was researched by using regular associated solution model and found that Cd-Na system is a weakly interacting [10]. In 2012, Awe and Olawole studied the correlation between bulk properties and surface properties in Cd-X (X=Hg, Mg) liquid alloys [11]. In 2013, thermodynamic, transport and surface properties of liquid In-Pb alloys have been investigated using the simple statistical model and found that liquid In-Pb alloy is weakly interacting and phase separating system [12].…”

We have used quasi-lattice theory to describe the mixing behavior of Bi-Pb liquid alloys at a temperature of 700K by computing thermodynamic functions and structural functions. The thermodynamic functions includes free energy of mixing (GM), activity (a), heat of mixing (HM), entropy of mixing (SM). The structural functions includes concentration fluctuation in the long-wavelength limit (Scc(0)) and chemical short range order parameter (α1). Most of the computed values are in good agreement with the experimental data. The pair-wise interaction energies between the species of the liquid alloys play important role and are found to temperature dependent. Theoretical analysis suggests that Pb3Bi complex exists in the liquid state at 700K. And, it has hetero-coordination (i.e. ordering) nature but is of weakly interacting in nature.
