X-ray computed tomography of a titanium aerospace investment casting

(in lingua inglese)
It has been demonstrated in this case study that very useful information can be obtained from automatic analysis of X-ray microCT scans of a casting. The simplest result is a stack of 2D slice images which provides a clear view of the inside of the part, especially for quick inspections of large numbers of parts. This requires no special software. Automated analyses include defect analysis, wall thickness analysis and part to CAD comparisons, which were demonstrated here. These automated analyses require high image quality and image artefacts affect the potential to apply these properly, which limits the size and density of the samples achievable for this type of analysis.
