The Ti6Al4V alloy specimens are processed with laser shock peening technology by nanosecond laser with a square laser spot. The hardness near-surface region and residual stress distribution in the top layer of Ti6Al4V alloy specimen are measured by Vickers hardness tester and hole drilling tester. The results show that the shock wave formed by laser shock peening can induce compressive residual stress in the top layer of Ti6Al4V alloy, which is beneficial for the improvement of fatigue life of Ti6Al4V alloy when it is used in aviation. The hardness of the near-surface region increases slightly in this research.
