Abstract

The observed asymmetry in the properties of mixing of MgSn alloy in molten state is successfully explained on basis of the quasi-lattice model. It has been utilized to determine the free energy of mixing, entropy of mixing, heat of mixing, the concentration- concentration structure factor in long wave-length limit [Scc(0)] and the Warren Cowley short range order parameter (α1) of MgSn alloy in molten state at 1073 K. The analysis suggests that heterocordiantion leading to the formation of chemical complex Mg2Sn is likely to exist in the melt but is of a weakly interacting in nature. The interaction energies between the species of the melt are found to depend considerably on temperature and the alloy is more ordered towards Mg rich region
