Microsegregation refers to the processes of solute rejection and redistribution at the scale of the dendrite arm spaces in the mushy region of a solidifying alloy. A representative geometry for a microsegregation analysis is the half-arm spacing in a `platelike' morphology. Models of microsegregation are based on a solute balance within this domain. The range of available models for microsegregation are discussed.
