Abstract:

Various methods of imaging defects were used on a titanium casting 4 in. 100 mm thick. The techniques, all involving acoustic waves, were C-scan, isometric projection, scanned holography, and a new method called stereo-acoustic imaging. The results are compared, and the latter method is shown to provide a true three-dimensional image of the material volume. Author
