| 英文摘要 | Nanostructured surface layer was synthesized on an AISI 304 stainless steel by using surface mechanical attrition treatment (SMAT), the microstructural evolution was examined by using the transmission electron microscope (TEM). A grain refinement mechanism was proposed as follows: dislocations slip in the {111} plane and intersect to form dislocation grids. One-system twins form and develop gradually to multi-system ones. Twin-twin intersections reduce the grain size and induce martensite transformation. With the increment of the twin systems and the enhancement of the twin intersection activities, grains are further refined. Finally, nano-scale martensite phase with equaixed shape and random crystallographic orientations forms upon the much larger strain, high strain rate and multidirectional repeated loads. |
