摘要
文 [1]对 LY12 (2 0 2 4 ) T6 2薄板铆钉孔进行激光冲击处理 ,装配成铆接结构后发现其疲劳寿命有稳定地提高 ,本文通过对疲劳断口的宏观和微观形貌的分析 。
In last paper,rivet holes of 2024T62 Sheet were shock processed by intense pulse laser before fitted in,the fatigue life of laser shock processed rivet joints are improved on those without LSP,the mechanism of laser shock strengthening rivet joints was investigated in this paper by micrography and macrography of fatigue fracture.
