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.
