Conclusions 1.The reduction in thermal cycling resistance of austenitc chromium-nickel steel in the low-cycle loading region as a result of irradiation by fast neutrons is connected with its radiation embrittlement, and an increase in thermal cycling resistance in the multicycle region is connected with radiation strengthening.2.The difference between the resistance to thermal fatigue of irradiated and unirradiated steel decreases with an increase in test temperature, which is connected with processes of transformation and annealing of radiation defects. This process is also responsible for the stronger time-dependence of thermal cycling resistance of irradiated steel.3.Dose dependences established for strength and ductility of austenitic chromiumnickel steels are based on processes of radiation strengthening, embrittlement, and high-temperature loss of strength. These dependences, combined with deformation criteria for low-cycle failure, make it possible to estimate the long-term thermal cycling resistance of steel taking account of radiation damage. |
