X-ray Computed Tomography (CT) is a non-destructive evaluation method that provides three-dimensional imaging and quantification of materials. CT is commonly employed as a characterization technique for measuring porosity, phase compositions, and other defects like cracks or impurities. Advancements in CT technology and software analysis tools have enhanced the usability of CT as a method that overcomes prior CT limitations and technical challenges inherent to other characterization techniques. This talk will present case studies demonstrating advanced scanning and analysis techniques. Phase contrast enhancement improved edge detection of carbon fiber composites for fiber orientation quantification. Tolerance deviation analysis illustrates a critical capability for part certification of additively manufactured parts by comparing the designed and as-built parts. Dual-energy scanning successfully segmented phases with only an 8% attenuation difference between aluminum and silicon carbide. Quantitative results for each case will be discussed that demonstrates the benefits and insights gained through using these state-of-the-art capabilities.
