THERMODYNAMIC STATE FUNCTIONS OF INTERFACIAL SEGREGATION
AND THEIR ROLE IN THE COMPENSATION EFFECT

P. Lejček and S. Hofmann

Abstract

The physical meaning of thermodynamic state functions appearing in the LangmuirMcLean segregation isotherm the standard Gibbs energy of segregation, the Gibbs energy of segregation, the excess Gibbs energy of segregation, and the effective Gibbs energy of segregation, and their enthalpy and entropy constituents is elucidated. As an example, the importance of standard thermodynamic functions is demonstrated for the compensation effect.
