THERMODYNAMICS OF INTERSTITIAL SOLID SOLUTIONS WITH REPULSIVE SOLUTE-SOLUTE INTERACTIONS

Abstract

The quasichemical treatment published in 1937 by Lacher is recommended as the best available statistical treatment of interstitial solutions. It is shown that the quasichemical method is exact in certain important cases, and the error in other cases is discussed. An expression for the excess entropy of interstitial solutions with excluded sites is derived from the quasichemical expression. The conditions of reliability of this expression, and of other simplified treatments which have previously appeared, are evaluated by comparison with the quasichemical result. An analysis is given of the excess partial entropy of hydrogen in V-H, Nb-H, and Ta-H solutions. (Author)
