Solidification

  Eutectic      
 
Learning Objectives:
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.
