Abstract: Microstrains in three series of the samples made of various stainless austenite dispersion-strengthened steels, which are used to produce different construction parts in reactor engineering, have been studied by high-resolution neutron diffraction. The influence of the temperature and duration of thermal treatment on the precipitation of particles of the dispersion-strengthening phase and on the variation in parameters and microstrains of the crystal lattice has been investigated. An increase in microstrain with the drop of coherence has been observed for all studied steels.
