A zoom on a grain boundary in the 32 grain microstructure, c.f. Figs. 5 and 10 (the subgrain boundary appears in the lower right quadrant of the microstructure in those figures). From left to right, top to bottom, the orientation field around the grain boundary is shown immediately after deformation, at 500, 1000 and 3600 s, respectively. The grain is on the edge of the simulation box, and so the change in the profile to the very right in the figure is likely due to ordinary grain boundary migration. However, a little to the left there is a small bulge that appears which can not be explained by the geometry
