From: Microstructure evolution in deformed polycrystals predicted by a diffuse interface Cosserat approach
The microstructure after 2 h of constant shear deformation at moderately elevated temperature. The simulations allow one (left) or four (right) possible active slip systems. From top to bottom the images show the orientation field, the phase-field \(\phi \) and the curvature \(|\nabla \theta |\). The original grain boundaries are outlined in black. The initial microstructure is the same in both cases
