| Abstract Scope |
Understanding the coupling effects of radiation and corrosion on structural materials in liquid metal environments is critical for the deployment of advanced Gen IV fission and fusion reactors. In this study, simultaneous irradiation and corrosion tests were conducted on various Fe-based materials and ceramics, including Fe-20Cr, SS316L, Fe-25Ni-16Cr-4Al, Fe-36Ni, and SiC, exposed to oxygen-poor liquid Pb-4Bi at 675°C using an in-situ proton beam. The results reveal distinct corrosion mechanisms across the materials, with varying Ni concentrations acting as the key miscible element that governs the extent and morphology of liquid metal penetration. Irradiation was found to promote the initiation of liquid metal penetration of SS316L, Fe-20Cr, and Fe-25Ni-16Cr-4Al, attributed to radiation-enhanced wetting. However, minimal effects of irradiation on corrosion were observed for Fe-36Ni and SiC at 675°C. Both qualitative and quantitative analyses were employed to facilitate drawing these conclusions. |
