A theoretical investigation of the energetics and its effect on the alloying behaviour of Cd–Hg and Cd–Mg liquid
alloys have been carried out with the aim of correlating their bulk and surface phenomena. Using the
Quasi-chemical approximation for regular solution model, our results indicate that Cd–Hg and Cd–Mg are
weakly heterocoordinated both in the bulk and on the surface. We observed that the degree of chemical
order in Cd–Mg liquid alloy is more than that of Cd–Hg liquid alloy
