Corrosion characteristics of materials in Pb–Bi under transient temperature conditions

Study of iron structure stability in high temperature molten lead-bismuth eutectic with oxygen injection using molecular dynamics simulation

“…The corrosion system (Fe-O-PbBi) in the study has dimension 123 124 125 3 where iron is in the center of the liquid PbBi. The oxygen atoms distributed in the liquid PbBi evenly with certain small consentration, as in Table 2.…”

“…These reactors have safety advantages because it does not need to be kept under pressure, possibility of higher power density than traditional coolants. However, this reactor also has major disadvantages, for example: the difficulty associated with inspection and repair of reactor materials immersed in liquid metal (PbBi) and also high corrosion of used structural materials immersed in that liquid metal [1,2,3].…”

Structural, mechanical and magnetic properties studies on high-energy Kr-ion irradiated Fe 3 O 4 material (main corrosion layer of Fe-based alloys)

“…in liquid LiPb and PbBi alloy has been investigated, and the corrosion results show that these Fe-based steels suffered more serious corrosion attack from 480°C to 550°C [16,17], and the oxide layer (Fe 3 O 4 and Cr x Fe 3Àx O 4 ) at steels' surface with about 5 lm thickness formed after 1000 h corrosion (see next part). Generally speaking, during the stage degeneration of material, the formation of corrosion layer is one of the important features of the process [18]. Cracking, blistering, embrittlement and other changes in materials may be induced by corrosion layers, http://dx.doi.org/10.1016/j.jnucmat.2014.09.027 0022-3115/Ó 2014 Elsevier B.V.

Study of Liquid Lead Corrosion of Fast Nuclear Reactorand Its Mitigation by Using Molecular Dynamics Method

“…This crucial problem has presented a critical challenge in application of lead coolant for fast reactor design. Then to handle the corrosion attack we need a way of reducing the corrosion rate or by creating and exploring novel materials [2], [6], not only under normal condition but also in the temporary anomalous condition especially for safety of heat transfer systems [5]. Meanwhile many experiments [2]- [8] about liquid lead/lead alloy corrosion have been reported, however a full understanding and how to manage corrosion are still not completed, yet.…”
