After studying this section,
the user should be able to:
- Relate the phase diagram to free energy curves for a typical eutectic system.
- Predict the minimum lamellar spacing for a given undercooling of the growth front.
- Explain in free energy terms why a spacing larger than the minimum facilitates advance
of the growth front.
- Predict the most likely lamellar spacing for a given growth velocity (extremum growth).
- Describe why some eutectics exhibit larger and more variable lamellar spacings than
predicted.
