Laboratory diffraction contrast tomography (LabDCT) is a laboratory-scale x-ray microtomography technique that can be used to non-destructively map grains and grain boundaries in 3D. The fidelity of grain mapping significantly depends on the quality of grain reflections obtained from the illuminated volume of the specimen. In this article, we report the application of a novel forward modeling approach...
Structural materials are subjected to combinations of stress and corrosive environments that work synergistically to cause premature failure. Therefore, studies on the combined effect of stress and corrosive environments on material behavior are required. Existing studies have been performed in two dimensions that are inadequate for full comprehension of the three-dimensional (3D) processes related...
X-ray tomography has provided a non-destructive means for microstructure characterization in three dimensional (3D) and four dimensional (4D) (i.e., structural evolution over time), in which projections of a material’s structure are typically reconstructed using the filtered-back-projection (FBP) method or algebraic reconstruction techniques. The reconstructed images are typically segmented to conduct...
