Abstract [en]

The modelling of phase transformations, once the nucleation event has occurred, may involve tedious computations but nevertheless methods based on sharp and diffuse interfaces have been quite successful and led to a deeper insight even in complex multicomponent materials. On the other hand nucleation is much more difficult to model. The difficulties stem from deficiencies in our fundamental understanding of nature, from lack of physical knowledge as well as problems involving computational efficiency. In the talk the classical theory of nucleation as well as various modifications over the years will be reviewed. Special emphasis will be given to the thermodynamics of small clusters, kinetics of fluctuations, multicomponent effects, and the rate of nucleation.
