Assumptions/conditions for non-equilibrium solidification
no diffusion in the solid complete diffusion in the liquid equilibrium at the solid/liquid interface
Coring
regions of metal with different concentrations in the core than on the outside

Composition of solid formed given by the Scheil’s equation

Assumptions/conditions for equilibrium solidification
complete diffusion in the solid
complete diffusion in the liquid
Outcome when liquidus and solidus are straight
