| 摘 要： | 研究了高功率密度激光冲击处理对Ｌｙ１２ＣＺ铝合金力学性能的影响，研究结果表明激光冲击处理可大幅度提高铝合金的疲劳寿命，疲劳寿命的提高是由于微观组织中位错密度的明显增加，使得材料表层的强度和硬度也明显增加所致。

| Abstract: | The effects of high power density laser shock processing on mechanical properties of Ly12CZ aluminum alloy have been studied. The results show that fatigue life of Ly12CZ after laser shock processing can be improved. The improvement of fatigue life is due to the increment of dislocation density in microstructure, resulting in abvious increases of strength and hardness. |

| Keywords: | laser shock processing fatigue Lyizcz aluminum alloy dislocation density nailing method |
