X-Ray Maps of a Crack along the Surface of Alloy 500 Tubing (image) NACE International Share Print E-Mail Caption Image caption: This series of images show the x-ray maps of a crack along the surface of Alloy 500 tubing. In (a), the absorption map shows parts of the physical crack; (b) shows the grain orientations along the crack; (c) shows compressive stresses in blue as a result of the crack opening; (d) shows the crack's propagation path on the tubing via scanning electron micrograph, along with a "trench" created by ion beam for easier imaging of a crack cross section; (e) shows the crack opening.
