Evaluation of Internal Stresses using Area Detectors

An area detector technique has to be applied to the strain scanning method for the coarse grains. A new rotating slit system was designed for a 2-dimensional (2D) detector strain scanning method. The rotating slit system focuses the 2D detector on the center of the goniometer, an d the gauge volume is made by the rotating slit system. The stress measurements were examined by the rotating slit and 2D detector. The measured diffraction spots shifted for the 2D strain scanning. The magnitude of the shift of t...

Study on Evaluation of Internal Stresses using Area Detector

This paper describes a stress measurement using a direct-method. In the direct-method, the stress is measured by the normal incident X-ray beam, one exposure and an area detector. The direct-method needs a narrow incident beam, so that the beam was made by the graphite monochromator. The welded specimen of SUS316L and the shrink-fitted specimen of SUS304 were prepared, and the distributions of the residual stresses of these specimens were measured using the direct-method. It was possible to measure the weld ...
