“…The main advantages of diffraction methods are their non-destructive character and the possibility of micro-and macrostress analysis for multiphase and anisotropic materials. Neutron and X-ray diffraction experiments with multiple reflections were successfully used to determine grain stresses directly from the lattice strains measured for groups of crystallites contributing to different reflections [2,3]. In another method, the so-called stress orientation distribution function (SODF) was determined from the lattice strains measured for many orientations of the scattering vector using different hkl reflections.…”

X-ray diffraction method was applied to measure residual stresses in deformed and annealed polycrystalline austenitic steel. An elastoplastic deformation model was used in analysis of experimental data. As the result, the orientation distribution function of grain stresses, created during elastoplastic deformation was determined and presented in the Euler space. An important decrease of the first and the second order residual stresses was observed during recovery process. It was found that the magnitude of the stresses decreases, while their distribution between different grain orientations remains almost unchanged.
