Abstract
A new methodology for identification of two to three major associates in liquid binary metal solutions with negative deviations from Raoult’s law was used in the model of ideal associated solutions. Minimum error identification was achieved in the case of determining the equilibrium constants between associates and monomers at the concentrations of the components of solutions in which the concentration of associates receive the maximum values (“peak” concentration). Calculated thermodynamic properties of associates were compared with standard thermodynamic proper-ties of the respective intermetallides on alloys Fe – Al and Fe – Si at 1873 K.
