Abstract

A step-by-step procedure to determine the quality of ingots has been developed. This procedure is built on the reduced pressure test and is designed to guide the foundrymen to decide (1) whether the lot of ingots should be accepted and/or (2) what remedial liquid metal processing should be done to bring the melt to the desired levels. A case study on two aluminum alloy A356 ingots is also presented. The results show wide variability in the initial quality of the ingots. Moreover, traditional metallographic techniques to characterize the quality from the slice of the reduced pressure test sample have been shown to provide similar results to those obtained from computerized tomography.
