Abstract

In this paper, examples are given of how calorimetric values can givegreater certainty to phase equilibria calculated from thermodynamic data. Errors that may arise when phase diagram evaluations are carried out largely from the basis of Gibbs energy information only are illustrated by reference to recent evaluations of the Ti-Si system and the resulting calculated oxidation behaviour of titanium silicides. The importance of calorimetric values for calculation of metastable phase equilibria is demonstrated by results of work on the AlN-TiN hard-metal coating system. Finally, suggestions are made with regard to areas of work where calorimetric data are urgently needed.
