Abstract
In this paper we present the results of neutron diffraction investigations of the residual stress gradient around a stainless steel - zirconium alloy interface in a bimetallic adapter. This part is used in some structures of RBMK-type reactor channels. The stresses in this component arise due to various manufacturing processes and the thermal expansion factor mismatch between the two alloys. The residual stress distribution within stainless steel part and the residual stress gradient close to the interface were investigated. The experiments were carried out on the Pulse overlap time-of-flight diffractometer (POLDI) [1] (Paul Scherrer Institute, Switzerland) and the Fourier stress diffractometer (FSD) [2] at the IBR-2 pulsed reactor (Frank Laboratory of Neutron Physics, JINR, Dubna, Russia).
