X-ray computed tomography of a titanium aerospace investment casting

Abstract

This case study demonstrates the type of non-destructive analysis possible using X-ray micro computed tomography (microCT) for a titanium aerospace investment casting of 225 mm in its longest axis. The advantages of the method are highlighted while the limitations are also discussed. Recently the method has become more accessible and affordable due to multi-user service facilities and the analysis has become simpler due to software and hardware improvements. This case study demonstrates a typical analysis including defect detection, wall thickness and part to CAD comparison, which can be done in less than 4 h, while simpler results are possible in under 1 h. This will be particularly useful for industries requiring quick but detailed non-destructive analysis.
