Solidification

  Redistribution      
 
Learning Objectives:

After studying this module, the user should be able to:

  • Define the partition coefficient.
  • Derive the equation for steady state partitioning of solute at an advancing planar front.
  • Calculate segregation profiles after solidification with uniform liquid concentration.
  • Explain how diffusion in the solid affects segregation profiles and leads to limiting cases of lever rule and Sheil equation.
  • Predict the segregation profile after a single zone melting pass and understand how this will change after multiple passes.
