Abstract
This article presents the results of a nondestructive investigation of 319-aluminum alloy casting samples using scanning acoustic microscopy (SAM). Subsurface structure is inspected with a high frequency LEITZ ELSAM acoustic microscope and the lower frequency desktop SAM is used for a bulk structural investigation. This analysis reveals that SAM can be used to reveal the grain structure, constituents, inclusions and the porosity of aluminum castings. Results also indicate the feasibility of using SAM to study various structural transformations that occur during solidification and heat treatment processes.
