It is shown that during subcritical annealing, austenite pools are pref-erentially nucleated at prior austenite boundaries and martensite packet boundaries,and then austenite lamellae form at lath boundaries accompanied by cementite pre-cipitation and dissolution. The lamellar austenite growth along the lath and themartensite packet boundaries is beneficial to the decrease of both the interface andthe strain energies which are necessary for austenite formation. As a result, thelamellar ferrite-martensite dual-phase structure is developed after quenching.
