A model for the analysis of enthalpies and entropies of liquid binary alloys

Abstract

The automatic treatment of calculations of chemical equilibrium in homogeneous phases requires analytical representation of the enthalpies and entropies of mixing of the components; therefore various approaches have been investigated, including in particular an attempt to find significant models. The ‘surrounded atom’ model provides a satisfactory method of representing all the thermodynamic characteristics of mixing in binary alloys, on the basis of four adjustable parameters.
