As part of ongoing collaboration with the Madrid Institute for Advanced Studies Materials Institute, doctoral scholar Eugenia Nieto-Valeiras completed a six-month term with the Chawla Research Group. Eugenia's focus is on the modeling and simulation of plastic deformation in polycrystalline metals, and her work at Purdue bridged the gap between 2D and 3D models. Diffraction contrast tomography, possible with the XRadia Versa 620, was compared to electron backscatter diffraction results to achieve accurate grain mapping in various alloy systems. Three-dimensional grain maps make it possible to enhance finite element analysis models of plastic deformation, providing rich information about the effects of grain boundaries.
