Abstract

In Al alloy castings, it is often not microstructure, but entrained defects in the form of bifilms that dominate mechanical properties. To assess their effect, this study targets a new quantification of metal quality, measuring the lengths and number of bifilm defects as determined from the microstructural section of a reduced pressure test (RPT) sample.
