| Abstract: | Laser shock processing (LSP) is a new technology for strengthening materials. This paper investigates LSP used as a method to improve the fatigue life of aluminum alloys. The key technology of LSP is studied. The effects of LSP on the fatigue life of aluminum alloy are also researched. The results show that the fatigue life of aluminum alloy treated by optimized LSP parameterscan be increased significantly. |
