Performance of Sc-Y-ODS variant of Eurofer steel in stagnant PbLi at 600 C

Popis výsledku v původním jazyce

This paper represents a part of the research of structural materials for fusion systems. The performance of a conventionally formed Eurofer-97 steel and its Sc-Y-ODS variant developed by our group was assessed in a stagnant liquid PbLi environment. The experiments were performed at 60 0 degrees C for 50 0 and 10 0 0 hours, and the subsequent microscopical investigation identified a solution-based attack as the dominant corro-sion damage of both materials. The metal loss of the conventional Eurofer-97 steel was 66.2 pm after 10 0 0 h exposure, corresponding to a rate of 580 pm/year. In contrast, the ODS Eurofer variant strength-ened with various fine Sc-Y complex oxides showed a 70% lower corrosion damage, mainly owing to formation of a Sc-Y-rich Pb surface layer. To understand the degradation process in more detail, both materials were characterized before and after the PbLi exposure in terms of their microstructures and mechanical behavior including hardness, tensile, impact and static fracture toughness tests.(c) 2022 Elsevier B.V.
