REPORT


essor Mats Hillert during the preparation of this work and for his many helpful comments on the first and second versions of this article. The key reader’s suggestion of mentioning the difference in thermodynamic equilibrium conditions between fluid-fluid and solid-solid systems is acknowledged. This suggestion has led to the addition of the entire paragraph immediately before summary. REFERENCES 1. D.V. Ragone: Thermodynamics of Materials, John Wiley & Sons. Inc., New York, NY, 1995, vol.
