A metal solidification system consists of solid, mushy and liquid regions. In many systems the two phase mushy region has a fine scaled columnar dendritic morphology. Microscopic models of metal solidification systems focus on the mass diffusion (microsegregation) and movement of the solid/liquid interface in the dendrite arm spaces. In this paper the effects of macroscopic variables on the microsegregation predictions are studied. In particular, the effect of cooling and macrosegregation histories on the solid solute profile, the eutectic fraction formed and solid/liquid interface movement in the arm spacing will be investigated.
