Research Abstract

A diffraction spot trace method (DSTM) was proposed. The DSTM is a new technique to measure internal stresses, which combined a special rotating slit system and an area de-tector (PILATUS). The enough collimation of the special rotating slit system was examined from measuring the bending stress in a specimen of S45C. The bending stresses in the specimens of aluminum and magnesium alloys were measured using the DSTM. The ob-tained stress distributions corresponded with the applied stresses. The DSTM was applied to the measurement of the welding residual stresses. The residual stress map by the DSTM corresponded with the simulated results by a finite element method.
