Internal Friction and Elastic Study on Surface Nanocrystallized 304 Stainless Steel Induced by High-energy Shot Peening

Keywords： Surface nanocrystallization

The 304 stainless steel with nanostructured surface layer was successfully obtained by using the high-energy shot were dynamically measured by means of the vibrating reed apparatus. The results implied that different treatment time could induce different microstructure and distribution characteristic of defects in this kind of materials. It is also demonstrated that there is a transition layer between the nano-layer on surface and the coarse grain region inside.The transition layer obviously has certain influence on the overall mechanical properties.
