摘要：

The effects of micro laser shock peening (micro-LSP) on microstructure, microhardness, surface topography, and fatigue strength of 2A02 aluminum alloy are studied in the present work. The results show that micro-LSP can significantly improve fatigue strength regardless of a high surface roughness introduced by micro-LSP treatment. The fatigue strength enhancement is mainly attributed to the combined contribution of high-density dislocations in the slightly remelted surface layer, transition of precipitate, work hardening layer, and grain refinement induced by micro-LSP treatment. This study demonstrates the potential application of micro-LSP in the improvement of the service life extension of aircraft structural parts.
