Acquisition and analysis of 3D microstructural data takes a significant amount of time and computational resources, driving a need to determine the minimal amount of data necessary to be statistically significant. A new method to evaluate representative volume element (RVE) size, the smallest volume that statistically reflects the macroscopic properties of a material, is presented. Resolved shear stresses (RSS) are calculated from far-field high energy x-ray diffraction microscopy data of a sample of Ti-7Al loaded to 2.5% strain. Analysis of the RSS distributions reveal increasing levels of spatial homogeneity as the strain was increased, indicating that for the Ti-7AL tested, RVE size appears to decrease with the amount of deformation.
