The appearance of very small particles, or nuclei of the new phase, which are capable of growing

Die verskyning van baie klein partikels, of kerne van die nuwe fase, wat daartoe instaat is om te groei

The stage in phase transformation, where the nuclei increase in size, which results in the disappearance of some (or all) of the parent phase.

Die stadium van fasetransformasie, waar die kerne toeneem in grootte, wat daartoe lei dat sommige (of alles) van die ouer fase verdwyn.

Nuclei of the new phase form uniformly throughout the parent phase.

Kerne van die nuwe fase vorm gelykvormig deur die ouer fase

Nuclei form preferentially at structural inhomogeneities, such as grain boundaries, insoluble impurities etc.

Kerne vorm verkieslik by struktuele inhomogeniteite, soos korrel grense, onoplosbare onsuiwerhede ens.
