APPLICATION OF THE "SURROUNDED ATOM" MODEL TO THE DESCRIPTION OF THE THERMODYNAMIC PROPERTIES OF SOME METALLIC MELTS

Abstract

Previously at the Physical ChemistryDepartment of Taras Shevchenko National University of Kyiv G.I.Batalin and O.A.Beloborodova developed the method for calculating the thermodynamic properties of binary liquid metal alloys based on the "surrounded atom" model. This method gave the possibility to calculate the thermodynamic properties of binary systems through the entire composition range using very few experimental data. In present paper, this method was used for the melts of the Mn–Cu (In, Gd, Sm, Nd) binary systems, that demonstrate positive, negative or alternating in sign thermochemical properties. A good agreement between the experimental been demonstrated for these systems. The described technique can be widely used to predict the thermodynamic properties of metal systems yet unexplored.
