Abstract Scope Recent advances in high-energy x-ray diffraction microscopy (HEDM) have made three-dimensional non-destructive characterization of materials possible under a variety of experimental conditions. Near-field HEDM (nf-HEDM) data reconstructed with the forward-modeling method resolves orientations on the length scale of single microns, but as we show, experimentalists must take care to ensure accurate reconstruction of spatial features. Here, we quantitatively compare nf-HEDM reconstructions of a high-purity gold calibration cube to characterizations acquired with Electron Backscatter Diffraction microscopy, scanning electron microscopy, and synchrotron-based micro-computed tomography and demonstrate excellent correspondence between the techniques given proper forward-modeling procedures are followed. We also examine how errors in replicating the experimental parameters manifest within the reconstruction space. Understanding the nature of these errors is critical to researchers seeking to use HEDM to study spatially resolved critical events in microstructure.
