Topological aspects responsible for recrystallization evolution in an IF-steel sheet – Investigation with cellular-automaton simulations

• Curvature-driven subgrain coarsening simulations mimic recrystallization in IF-steel. After the simulation, texture components appear, as also found experimentally. Subgrains near non-intergranular HAGBs do not have a size advantage. Shear/deformation band nucleation occurs by matrix subgrains invading bands. When deformation bands intersect abutting kinetic and A cellular automaton algorithm for curvature-driven is applied to cold-rolled interstitial-free steel’s microstructure - obtained through electron backscatter diffraction (EBSD). Recrystallization naturally during due highly heterogeneous hence competitive growth among pre-existing (sub) grains. The spatial inhomogeneity of that takes place derives from large local variations sizes misorientations comprise prior deformed state. results show capillary-driven selective extent elongated grains are replaced equiaxed with no interior small-angle boundaries. Additionally, simulation certain intensify others vanish, which indicates preferential fashion relates crystal orientations’ topology. study early stages (i.e. nucleation) shows eventually recrystallize, exhibit topological characteristics at Successful mostly shear or narrow particularly regions where latter intersect.
