Abstract

From thermodynamic data on seven CsCl-type intermetallic nonstoichiometric compounds, the nature of the defects present has been deduced and the defect concentrations, and free energies, enthalpies, and entropies of defect formation have been calculated. The compounds discussed include AuCd, AgMg, AuZn, FeAl, NiAl, CoAl, and PdAl. It is shown that the thermodynamic activities across the entire homogeneity range of a compound may be computed from a knowledge of the defect structure and free energies of defect formation and interaction.
