The combination of experimental data and polycrystal plasticity modeling is a powerful tool to advance our understanding of the behavior of individual grains and how these interact. The present paper illustrates how much information a single three-dimensional x-ray diffraction experiment contains and how this may be analyzed and compared with model predictions. The data cover the elastic and plastic regimes (0.1%, 1%, and 5% strain) of a tensile experiment on a fully recrystallized stainless-steel sample. The number of bulk grains analyzed is on the order of 200. Specific phenomena considered are stress correlations across twin boundaries, stress states, and resolved shear stresses in the elastic and plastic regimes along with lattice rotations.
