Study on the Distribution of Residual Stresses for Nondestructive Marking by Laser Shock Wave

摘要：

The marking system by laser shock wave (LSW) based on liquid crystal mask, which differs entirely from marking by laser ablation (or laser thermal effect), was established. Two-dimension (2D) nondestructive markings based on liquid crystal mask were prepared by LSW, and the distribution of residual stresses in lasershocked region was measured and analyzed. The results showed that tensile residual stresses of sample surface were converted into compressive residual stresses by LSW, which is a nondestructive marking for aviation key parts.
