Abstract: In this paper we present the results of residual stress measurements on a perforator’s striker, which is used in the mineral resource industry. The stresses in this component arise due to various processes of heat treatment. The residual stress distribution in the material after isothermal hardening and after carburising was investigated. Three strain tensor components were measured at various depths. The microstress level was estimated from diffraction peak broadening. The experiments were carried out on the HRFD diffractometer at the pulsed reactor IBR-2 (Dubna, Russia).
