Fig. 5

The 32 grain microstructure before and after applied shear deformation. The initial values are shown to the left for \(\theta \) (top), \(\phi \) (middle) and curvature \(|\nabla \theta |\) (bottom). Top right shows the orientation distribution after shear deformation, middle right shows the corresponding phase-field \(\phi \) and bottom right shows the curvature. The true maximum value of the curvature norm is around \(|\nabla \theta |=1.7\) \(\upmu \mathrm {m}^{-1}\) but it has been capped off at 1 \(\upmu \mathrm {m}^{-1}\) for a better visualization. In the simulation, only one slip system was active, resulting in the formation of kink bands and subgrains
