The current work investigated the effects of aluminum on microstructure evolution during warm deformation in a strong but ductile Mn-rich steel. The cold-rolled steel was deformed by uniaxial tensile during inter-critical annealing at 600°C to 720°C. The microstructure was characterized by using transmission electron microscopy, X-ray diffraction and transmission Kikuchi diffraction. It was found that austenite transformation enhances the warm ductility of these steels. Besides, addition of aluminum changes the amount of austenite when inter-critical annealing and the stability of austenite after cooling. Both effects are crucial in designing strong but ductile steels for warm processing.
