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

The material of the specimen was austenitic stainless steel, SUS316L. The residual stresses in the specimen was introduced by a water j et peening (WJP). The change in the residual stress with thermal aging at 773K was measured by an X-ray stress measurement. The WJP res idual stresses were an equi-biaxial stress state, and the compressive residual stress did not decrease against the thermal aging. To i nvestigate dependence of the residual stress on a lattice plane, the WJP residual stresses were measured...
