Article Preview

X-ray diffraction method has been employed to calibrate the stress of 6082 aluminum alloy which has been widely used among modern industrial products. Based on elastic tensile conditions, by designing rod sample of uniform intensity calibration (RSUIC), the stress measurement by X-ray diffraction method has been verificated by using elastic tensile theory calculation method and electrometric method. The results show that the stress measured by the tensile stress theoretical calculation, electrometric method and X-ray diffraction method was in good accordance with each other. And the matching relation between the surface stress measured by X-ray diffraction and the internal stress is investigated. The research will lay a foundation for the application of iXRD stress instrument for nondestructive measuring the welding residual stress of aluminum alloy.
