Abstract
The traditional method of establishing phase diagrams relied on experimental methods. An alternate approach based on thermodynamic principles, known as the CALPHAD method, paved way to establish phase diagrams of even complex materials efficiently and reliably. Gibbs energy modelling is the central theme of the CALPHAD method. A brief account of the Gibbs energy models for phases relevant to ferrous systems are discussed. Examples of computed phase equilibria in selected iron-base systems are presented. Finally, some applications of the CALPHAD method relevant to the phase transformations in ferrous materials are given.
