000015365 520__ $$2eng$$aIn this of discussion, we present experimental observation on how gradient twins could enhance the strength of a twin-induced plasticity steel while retaining its tensile ductility. The mechanisms accounting for the exceptional mechanical properties were investigated at the microscopic level. The switch of twinning systems at the grain level during different deformation stages and the subsequent formation of hierarchical nanotwinned structure are responsible for the strengthening and toughening of the material. In addition, we show how gradient microstructure in 304 austenitic steel enhances its fatigue performance.
