Analysis of Casting Subsurface Structure Using Acoustic Microscopy
This article presents the results of an investigation of the subsurface structure in 319 aluminum alloy castings using a nondestructive scanning acoustic microscopy technique. This type of analysis can reveal the grain size, constituents, oxide inclusions and porosity. This method can also be used to study various structural transformations that occur during the solidification and heat treatment processes.
