Abstract
Intergranular(IG) fracture due to thermal treatment has been reported in a reactor pressure vessel(RPV) steel of Russian light water reactor in last decade. This is attributed to grain boundary segregation of phosphorus (P) or precipitation of carbide, etc.. This is a finding a difference in microstructure before and after IG..... More

Abstract
This study was conducted to investigate the effect of aging treatment from 300 °C to 420 °C on the mechanical properties of the pressure tube material at 310 °C, which is outlet temperature pressure tube in CANDU reactor. The short range ordering (SRO) phenomenon during aging process is confirmed by..... More
