In this work the influence of microscopic residual stresses on the diffractometric residual stress analysis was shown quantitatively. Experiments to investigate the dependency of the accumulation of microscopic residual stresses on precipitates within the matrix material were carried out successfully by neutron diffraction. Here, the high resolution neutron-Larmor-diffraction was used for polycrystalline samples for the first time. With Larmor diffraction information about microscopic stress field within different samples are accessible and comparable.
