Abstract

The important parameters in all descriptions of the kinetics of crystallization behaviour are the differences in free energy Δgv between the liquid (glassy) phase and the various stable and metastable crystalline phases. The various quenching techniques can be subdivided into those in which the cooling rate is determined by the heat diffusivity and those in which the heat transfer coefficient is important. The temperature gradient and the solidification rates are different in the two cases. An additional difference is the nucleation rate which is dependent on the degree of undercooling.
