The structure and stressed state of AMg6 alloy have been studied after laser shock processing without protective coating. The method of layer-by-layer X-ray structural analysis has revealed a correlation between the parameters of crystalline structure and the profile of residual stresses of the processed samples. After laser processing, the sizes of coherent scattering regions on the material surface decrease to 50 nm, the value of microstrains increases to 0.0019, and the average dislocation density increases to 4.7 × 1014 m–2. The profile and the depth of the residual compressive stresses depend on the power density, coefficient of overlapping of laser spots, and multiplicity of processing, reaching 2 mm.
