Abstract

The quasi-lattice model developed by Bhatia and Singh1-2 has been applied to understand the alloying behaviour of Au-Zn liquid alloys. The large negative values of ordering energy and chemical short range order parameter indicate heterocoordination in Au-Zn melt. The dip in concentration fluctuations in long wavelength limit and larger negative value of excess free energy of mixing at C = ½ suggest the existence of 1–1 type of complexes (AuZn) in the liquid alloys. This makes us believe that Au-Zn liquid alloys with symmetrical properties of mixing belong to strong interacting system.
