SUMMARY
Constitutional undercooling refers to the phenomenon occurring during solidification when the liquid phase is cooled below its freezing point ahead of the solid-liquid interface. This process can lead to homogeneous nucleation if sufficient nucleation sites are present. The discussion highlights the critical role of temperature gradients and nucleation dynamics in the solidification process, emphasizing the need for a thorough understanding of these concepts in materials science.
PREREQUISITES
- Understanding of phase transitions in materials science
