Low SFE in the medium Mn range is responsible for the poor mechanical properties of automotive steel. Addition of the Al enhances the overall SFE of the alloy. But the high SFE prefers recovery over recrystallization. So the present work is to study the recrystallization behavior of Al added low density medium Mn steel during annealing of the forged, hot rolled and cold rolled specimens at 1000ᵒC.The overall recrystallized fraction is evaluated from GOS calculation after the EBSD analysis. The cold rolled specimen recrystallizes faster than the forged and hot rolled specimen. It is due to the presence of larger stored energy during deformation. Crystallization rates are estimated from Johnson-Mehl-Avrami equation. It states about migration of the dislocation along the grain boundary during annealing.
