combination of strength and ductility as well as the lower density, aiming at developing more
affordable and safe vehicles with less fuel composition and air pollution. Fe-Mn-Al steel,
adding more Al and C elements into twinning induced plasticity (TWIP) steel, shows
amazing mechanical properties, corrosion resistant and weight reduction than traditional
steel. The mechanical properties and microstructure of Fe-27Mn-11.5 Al-0.95 C-0.59 Si steel …
