Abstract
An analytical treatment of the influence of coarsening by ripening on microsegregation is presented. Comparison of results from the model with data on Al-4.5 wt pct Cu and Sn-Bi alloys indicates that an overestimation of the reduction in microsegregation results if it is assumed that ripening proceeds throughout the solidification range. This is attributed to the changing nature of coarsening processes, in which coalescence processes predominate over ripening at higher volume fractions solid.
