Post-life ageing of austenitic chromium-nickel 304 steel elements of the fast neutrons
reactor equipment was carried out at a temperature above the operating conditions. The change in
the short-term mechanical properties of the material was investigated. The relationship between
the change in impact strength, fracture mechanisms and the morphology of carbide precipitates
was revealed.
Keywords: post-life ageing; austenitic steel; mechanical properties; fracture mechanisms; microstructure; carbides precipitation. |
