摘要: 

铅铋共晶(LBE)因其良好的物理性能和化学稳定性,成为铅冷快堆冷却剂的优选材料,但结构材料与高温液态LBE接触会发生性能的退化,而含铝奥氏体不锈钢(AFA)具有优异的耐腐蚀性能和力学性能,在铅冷快堆中具有重要应用前景。本文介绍了AFA钢概况,总结了元素成分、氧浓度和预氧化对AFA钢在液态LBE中腐蚀行为的影响,综述了AFA钢在液态LBE中的力学行为研究,讨论了AFA钢在液态LBE中的腐蚀和脆化机理,提出了当前研究中存在的问题,展望了未来的研究方向。

Abstract

Lead-bismuth eutectic (LBE) has emerged as the preferred coolant material for lead-cooled fast reactors owing to its good physical properties and chemical stability. However, many metallic structural materials are prone to degradation in liquid LBE at high temperatures. Among others, alumina-forming austenitic stainless steel (AFA) exhibits excellent corrosion resistance and mechanical properties. Thus, it has been recognized as a promising candidate structural material for lead-cooled fast reactors. This paper presents an overview of AFA stainless steel. The effect of chemical composition, oxygen concentration and pre-oxidation treatment on the corrosion behavior and the mechanical behavior of AFA steel in liquid LBE are summarized. The mechanism underlying liquid metal corrosion and liquid metal induced embrittlement of AFA stainless steel are also discussed. The existing challenges in current research and the future research issues are outlined.
