  • After strengthening two states of 7050,one kind of aerial aluminum alloy,T7451 and T7452 with laser shock processing device developed by ourselves,the alloys' surface stress and structure are measured.Test results show that there is large residual compressive stress on the surface and internal dislocation density.However S-N curve in fatigue test shows that the fatigue strength in increased more than two times under the condition of moderate load strengthening.

Abstract: After strengthening two states of 7050,one kind of aerial aluminum alloy,T7451 and T7452 with laser shock processing device developed by ourselves,the alloys' surface stress and structure are measured.Test results show that there is large residual compressive stress on the surface and internal dislocation density.However S-N curve in fatigue test shows that the fatigue strength in increased more than two times under the condition of moderate load strengthening.
