摘要: Laser shock peening (LSP) is a promising surface technique to improve mechanical properties. The effect of LSP on the microstructure, high-temperature properties and residual stress AZ31 alloy was investigated by 3D profilometer, transmission electron microscopy, x-ray diffraction, Vickers tester, respectively. results reveal that both nano-grain layer compressive were formed in after treatment. strength remarkably improved as tensile temperature below 200 °C. While has no obvious above 300 °C. Fractographs as-rolled LSPed alloys indicate quasi-cleavage fracture dominant model 200 °C, while ductile Additionally, strengthening mechanism treatment analyzed detail.
