Surface shot peening and annealing heat treatment were applied to the Fe-30Mn-3Al-3Si TWIP steel to achieve toughening. The effects of shot peening and shot peening combined with annealing on the microstructure of TWIP steel were analyzed by means of metallurgical microscopy, X-ray diffraction and t...
