| Abstract Scope |
Under constant conditions, e.g. temperature, pressure etc., a phase transformation will proceed until the equilibrium is eventually reached. The equilibrium state may be predicted by looking for the extremum in a thermodynamic state function and the thermodynamic properties of the system. Although the actual calculations may be tedious the underlying principle is straight forward. It may thus be tempting to look for an underlying principle that could be used to derive the governing equations allowing prediction of phase transformations and microstructural evolution. It has been suggested that one should look for an extremum in the entropy production of irreversible processes such as diffusion or heat flow. This topic has been discussed by several authors, e.g. Onsager, Prigogine, Kirkaldy and Cahn.
The aim of the presentation is to give an overview of topic and to discuss some key issues. |
