Abstract

Modeling the development of micro- and macrosegregation patterns and grain structures in the equiaxed solidification of metal alloys under the combined influences of melt convection and the motion of free solid has been the subject of intense recent research efforts. This article presents a summary of selected experimental and theoretical studies aimed at understanding the convective transport processes both for a single grain and at the scale of a casting. The need for much additional research is emphasized.
