APPLICATION OF THE CALPHAD METHOD TO MATERIAL DESIGN

The outline of the CALPHAD method, which has been developed to allevia te the difficulty in obtaining phase diagrams by experiments alone, is presented. This method enables calculation of stable and metastable p hase equilibria, as well as thermodynamic properties such as activity, enthalpy, driving force, and so on. Some examples of the calculated p hase diagrams, obtained by applying the CALPHAD method are reviewed, i n connection with the design of their microstructures. (C) 1998 Elsevi er Science B.V.
