Abstract In order to explore the influence of texture on the X-ray stress measurement of 6061-T6 aluminum alloy, this paper used X-ray for stress mea-surement of the preset stress on the surface of constant stress beam, using electron backscatter diffraction (EBSD) technology and crystal orientation imaging analysis technology to analyze the effect of texture on the number of diffraction crystals according to the angular relationship between grain orientation and incident X-ray beam. Further more, the effects of texture on the homogeneity of microscopic strain and microscopic stress were discussed. The results show that when the orientation of diffraction crystal was in the range of ψ=0—15°, the texture led to a decrease in the number of diffraction crystals, which caused differences of microscopic strain and microscopic stress among different diffraction grain groups, these differences made the measured change of diffraction angle unable to reflect the change of diffraction angle caused by stress, so the stress measurement accuracy was reduced.

Key words： stress measurement X-ray texture heterogeneity
