Abstract Scope |
In this study, we present a validation of a new modality of three dimensional x-ray diffraction (3DXRD) microscopy that can provide 3D maps with spatial resolution better than ~2 μm. The experimental parameters affecting the quality of the maps are optimized via a series of simulations with FABLE package’s PolyXSim software. In these simulations, 3D maps of a physically relevant phantom microstructure are simulated on a large field-of-view detector (15,000 x 15,000 pixels). The experimental requirements for obtaining certain number of grains with enhanced resolution are explored with respect to signal-to-noise ratio, pixel size of the detector and reciprocal space sampling. With the presented optimization, 3D maps of 1000 grains with average size of 1 μm can be obtained with an accuracy of ~0.3 μm in center-of-mass position with ~0.0045° in orientation. Depending on the progress, first experimental results will also be presented. |
