Generalised ‘Jackson–Hunt’ model for eutectic solidification at low and large Peclet numbers and any binary eutectic phase diagram

Based on the generalised ‘Jackson–Hunt’ model from Donaghey and Tiller for eutectic solidification of binary alloys, a relation between growth velocity, lamellar spacing and interface undercooling for any binary eutectic phase diagrams and any Peclet number is derived. This relation is then used to propose a generalised scaling law for eutectic growth. The predictions of this generalised scaling law are discussed for extremely different eutectic phase diagrams and compared with predictions made by the TMK-model for symmetrical phase diagrams.
