Including: Nucleation, Nucleating
In terms of solidifying alloys, when the alloy (or a phase of the alloy) nucleates it starts to solidify a few atoms at a favourable site. These tiny solid lumps encourage more liquid to solidify onto them and these nucleation sites grow. Many of these sites form within the liquid which finally will become dendrites.
