| Abstract Scope |
As the search for sustainable energy sources continues, Generation IV nuclear reactors are regaining global attention. A key challenge is the development of structural alloys capable of withstanding corrosion from hot liquid metals and radiation damage. Promising candidates for structural steels may come from an alternative research field: advanced high-strength steels (AHSS) originally developed for automotive applications. This approach could potentially eliminate the need for scarce and expensive elements such as nickel (Ni). Various alloys have been synthesized following this strategy and tested for corrosion resistance in liquid lead, exhibiting different behaviors depending on their microstructure and chemical composition, including variations in corrosion resistance and morphology. Radiation damage was also evaluated through heavy ion irradiation at different temperatures, revealing varying levels of defect accumulation in the microstructure. These results provide valuable insights and a foundation for future research. |
