Liquid metals represent an aggressive environment where selective degradation can attack structural alloys. Pre-oxidizing structural alloys, particularly those able to form alumina scales, have shown promise for Sn, Pb and Pb–Li concepts for fusion and fission applications. For Pb at 700 °C, a dramatic reduction in mass loss was observed for an alumina-forming austenitic (AFA) steel after pre-oxidation. Likewise, a ferritic FeCrAlMo alloy showed better compatibility in static Sn at 400–500 °C and flowing PbLi when pre-oxidized at 1000 °C to form α-Al₂O₃. Recent experiments with flowing PbLi at 675–700 °C has shown significant degradation suggesting that alumina-forming alloys are limited to ~ 650 °C in this environment. While the concept is promising, most experiments have been relatively short-term and long-term degradation mechanisms need to be evaluated.

液态金属代表了一种腐蚀性环境，在这种环境中，选择性降解会攻击结构合金。预氧化结构合金，特别是那些能够形成氧化铝鳞片的合金，已显示出用于聚变和裂变应用的 Sn、Pb 和 Pb-Li 概念的前景。对于 700 °C 下的 Pb，在预氧化后观察到形成氧化铝的奥氏体 (AFA) 钢的质量损失显着减少。同样，铁素体 FeCrAlMo 合金在 400–500 °C 下与静态 Sn 和在 1000 °C 下预氧化形成 α-Al ₂ O ₃时流动的 PbLi 显示出更好的相容性. 最近在 675–700 °C 下流动 PbLi 的实验表明，在这种环境下，形成氧化铝的合金仅限于 ~ 650 °C。虽然这个概念很有前途，但大多数实验都是相对短期的，需要评估长期降解机制。
