Abstract:

Two electron beam additively manufactured (EBAM) titanium specimens provided by the US Army Combat Capabilities Development Command Ground Vehicle Systems Center at the Tank-Automotive and Armaments Command, Detroit Arsenal, were inspected and evaluated using X-ray computed tomography (XCT). XCT scanning parameters and overall protocols used to achieve acceptable scan image results are discussed. XCT image results, including 2-D internal slices at select locations and 3-D sectioned visualizations, are also shown and discussed. The physical nature of the types of features found in these specimens are also described and discussed.
