Evaluation of activation energies and other properties from structural studies of liquid metals and their extension to liquid Ag-In alloy

Using a hard sphere reference system with square well attractive tail the structure factors are computed for pure metals and then extended to Ag-In binary alloy. The agreement between the theoretical and experimental values is good. Further new equations have been derived for the temperature variation of diffusion coefficients and they are applied successfully to pure metals and extended to the binary Ag-In alloy. The applicability of these equations is verified by evaluating the activation energies and comparing them with literature values for these systems. The chemical short-range order parameter has been computed as a function of composition for Ag-In system through structural studies in the long wave limit, which gives valuable information regarding the nature of the liquid alloy at various compositions.
