The predictive simulation of precipitate formation based on classical nucleation theory requires the precise knowledge of the interfacial energy as the most important and sensitive input parameter. Although the majority of researchers use this quantity as a fitting parameter to get precipitation kinetics simulation in accordance with experiment, recent developments in modeling provide a framework that allows for a prediction of interfacial energies purely from thermodynamic databases. In the present work, the models for calculation of the planar sharp interface energy as well as the further developments to account for interface curvature and diffuse interfaces as developed by the present authors is reviewed. Successful examples of application of the models are discussed in the second part of the presentation.
