ABSTRACT

The complex formation model first proposed by Bhatia and Hargrove [1] assumes the existence of chemical
complexes or pseudomolecules in liquid binary alloys. On the basis of this concept Singh and his coworkers [2-5]
have studied various thermodynamical properties of different binary alloys. We have also studied different alloys
within this framework [6-8]. The present paper envisages the study of some thermodynamic properties viz., Gibbs
free energy of mixing (GM), Enthalpy of mixing (HM) and Entropy of mixing (SM) of the alloy under study. The
results are in reasonable agreement with experiment and throw light on the ionic interactions of the constituent
atoms leading to the alloying behaviour of the alloys under investigation.
