Feed metal paths enable visualizing the directional solidification of a casting. It flows microscopically along thefeed paths from regions that solidify later, to regions that solidify earlier (along highest temperature gradients) tocompensate the solidification shrinkage. Ideally, feedpaths should end inside a feeder. Long and hot feedpathsconverging inside the casting imply a local hot spot that can result in a shrinkage porosity defect. Short and coldfeedpaths are usually harmless.The feed paths from casting interior to surface were computed and displayed. Feedpaths were obtained in XZ plane. They ended inside a feeder. Fig. 11showsfeed metal pathsin 3D and in cross section, all converging inside the feeder thereby indicating directional solidification.
