Effects of Neutron Flux and Irradiation Temperature on Irradiation Embrittlement of A533B Steels

Source

Irradiation embrittlement of A533B steels with low copper contents were investigated from the point of dose rate and irradiation temperature effects. Change of neutron flux in the range from -1012 to -1013 n/cm2/s (E> 1MeV) did not have a significant effect on the embrittlement. Irradiation temperature change of 1°C resulted in the transition temperature shift (ΔT41J) of about 1°C and yield stress change (Δoy) of about 0.8MPa. Factors that might affect the embrittlement of low copper steels are also discussed.
