Описание к видео Crystallisation | Solidification of metals | Supercooling & nucleation | Microstructure formation

In this video, we look at the phenomena of supercooling and nucleation, both of which are prerequisites for the solidification of liquids and melts, respectively.

03:57 Supercooled water (freezing rain)
05:01 Heterogeneous nucleation
06:08 Homogeneous nucleation
06:57 Influencing nucleation by supercooling
