A significant step in the development of CALPHAD took place between 1985 and 1991 when SGTE developed and published its database for the pure elements [1]. This database now forms the basis for almost all thermodynamic assessments for alloy systems and is the backbone of all commercial thermodynamic databases, which are widely used by materials scientists for the prediction of materials properties and also for the control of industrial plants and processes. However, now, there is growing awareness that these data and the way in which they are modelled will not be suitable for the needs of the materials science community for the next 25 years. A collaborative international research program is underway towards the development of a new set of data based on more physically realistic models to represent the variation of the thermodynamic properties of the crystalline and liquid phases with temperature and composition. In the present talk we will discuss the new models based on the results of a series of “Ringberg” workshops [2] and highlight some of the issues the assessor faces during critical evaluation of experimental data using some recent examples where they have been applied.
