Abstract
Models for predicting interdendritic cavity defects, from which cracks can easily propagate, are necessary for the advancement of casting processes. This article shows that the location and severity of interdendritic cavity defects can be predicted using methods based on thresholds for interdendritic liquid metal flows. A short review on cavitation phenomena is presented and future directions are identified.
