Coarse grain
ln a strain scanning method with hard synchrotron X-rays, the stress measurement of materials with coarse grains is one of challenging assignments. As measures of the coarse grain problem, an advanced strains canning method was proposed in this paper. In this method, the gauge volume is scanned under rotating the sample, consequently the scanning stage has to set on the rotating stage. The special stage, which we had made using as lip-ring mechanism, enabled the proposed method. The diffraction angles of the annealed S45C sample were measured by the strain scanning method with a rotation. The diffraction angles were constant and the surface aberration effect did not appear. Therefore, the strain scanning method with arotation demonstrated the excellent correction of the surface aberration effect. The diffraction profiles of the shot-peened austenitic stainless steel of SUS304L were measured by the strain scanning method without arotation, but the residual stress distribution was not obtained due to the distorted profiles. On the other hand, the residual stress distribution of the same specimen could be measured using the strain scanning method with a rotation. Asaresult, this method is useful for the stress measurement of coarse grains.
