“…Among these, irradiation and thermal aging inducing the embrittlement of RPV materials requires special attention. While most of the previous research were focused on the neutron irradiation [2][3][4]. The effects of thermal aging still call for more attention.…”

Effects of thermal aging on tensile and Charpy impact properties in 16MND5 steel was investigated, which were aged at 500°C for 0 h, 1000 h, 3000 h, 5000 h. A significant decrease in the yield stress and ultimate tensile strength was observed after thermal aging, while the elongation exhibited a slight decrease follow by an increase aged for 5000 h. What's more, the ductile-to-brittle transition temperature (DBTT) showed a remarkable increase with the prolongation of thermal aging duration. These facts indicate thermal aging caused embrittlement of the steel, which was further investigated by microstructure observation of SEM. The results show cleavage fracture after thermal aging. Furthermore, experimental results at 350°C thermal aging temperature originated from the previous literature were used to analysis the effect of thermal aging temperature. Thus, thermal embrittlement should be taken seriously.

“…Proton irradiation was used to simulate neutron irradiation since it imparts same damages as neutron irradiation and also can provide short irradiation time and high damage rate [9,10]. And also, the penetration depth and transmutation in proton irradiation is very less [11,12]. Temperature dependent magnetic properties were also investigated in order to check the possibility of a hightemperature operation.…”

In this study, we report on an investigation of proton radiation resistance of 410 martensitic stainless steels under 3 MeV proton with the doses ranging from 1.0 × 10 15 to 1.0 × 10 17 p/cm 2 at the temperature 623 K. Vibrating sample magnetometer (VSM) and X-ray diffractometer (XRD) were used to study the variation of magnetic properties and structural damages by virtue of proton irradiation, respectively. VSM and XRD analysis revealed that the 410 martensitic stainless steels showed proton radiation resistance up to 10 17 p/cm 2 . Proton energy degradation and flux attenuations in 410 stainless steels as a function of penetration depth were calculated by using Stopping and Range of Ions in Matter (SRIM) code. It suggested that the 410 stainless steels have the radiation resistance up to 5.2 × 10 −3 dpa which corresponds to neutron irradiation of 3.5 × 10 18 n/cm 2 . These results could be used to predict the maintenance period of SUS410 stainless steels in fission power plants.
