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 in the bands.•When deformation bands intersect abutting subgrains have kinetic and size advantage.
