Radiation strengthening and microstructure evolution in austenitic chromium-nickel steel under the effect of the irradiation of different types
The results of the study of radiation-induced strengthening and microstructure evolution in the 0Kh18N10T austenitic stainless steel irradiated by neon ions (with energy of 230 MeV) and neutrons (En > 0.1 MeV) are presented. The experiments were performed in an inner beam of an U-400 cyclotron in Dubna and in an EWA reactor (Institute of Atomic Energy, Swerk, Poland). The dependence of the mechanical properties on the dose of irradiation-induced damage was determined. Changes in microstructure are studied by TEM, and the density of the aggregates of irradiation-induced defects was determined as a function of the dose. The data obtained are discussed in terms of mechanical properties and microstructure characteristics.
