As part of modelling the microstructure evolution in an intercritical-annealing cycle, a 3D multi-phase field model has been employed to simulate recrystallization during heating of a low-carbon steel that is used to produce commercial DP600 grade. The cold-rolled microstructure obtained from metallographic observations is used as the initial st
