Being the lightest of all structural metals, role of magnesium alloys increases especially for automotive and aerospace industries, where weight reduction has priority for fuel efficiency. AZ31 (3 wt % Al, 1 wt % Zn, balance Mg) alloy strengthened by grain size reduction via recrystallization is the most common wrought product among all magnesium alloys. In the present study, recrystallization mechanism of AZ31 alloy is examined by isochronal differential scanning calorimetry (DSC) runs at various heating rates complemented by scanning electron microscopy and hardness measurements. Microscopically determined recrystallized fraction is correlated with extent of softening in accord with the isochronal DSC peaks. Finally, it has been predicted that, the recrystallization curves observed to deviate from sigmoidal nature, which is usually overlooked, imply a spatially bi-modal recrystallization behavior that originates from the presence of low temperature dynamically recrystallized regions prior to annealing.
