IRRADIATION EFFECTS IN STRAIN AGED PRESSURE VESSEL STEEL

摘要

Tensile specimens, Chirpy-V notch and subsize Impact specimens of aluminium killed carbon manganese steel have been irradiated at 160 - 190 C in the reactor G1. The total neutron dose received was 2.4x 1018n/cm2 (> 1 MeV). Specimens were prepared from normalized plate and from strain aged material from the same plate. It was found that the changes in brittle ductile transition temperature due to neutron irradiation and those due to strain ageing must be considered additive.
