Heterogeneous nucleation - the most common type of transformation
•
These locations have lower energy barrier for nucleation
○
Nucleation takes place at favourable locations in the volume such as
surface, grain boundaries, inclusions
•
Crystallization begins on impurity particles (added), mold walls,
ect
