X-ray computed tomography (CT) of casting defects present in samples of a cast aluminum alloy have been analyzed to obtain morphologic parameters. 3D finite element meshes have also been generated from the CT images in order to compute the stress field at the vicinity of each defect. Correlations between the fatigue properties of the samples, the morphologic parameters, and the stress fields are analyzed to determine the predominant parameter.
