Multimodal In Situ X-ray and Electron Microscopy Reveals Temperature-Dependent Corrosion Mechanisms of Ni-20Cr Alloy in Molten Salt

摘要: Understanding alloy behavior in molten salt environments plays an important role in developing sustainable energy systems. Specifically, a molten salt reactor (MSR) is considered as a safe and efficient nuclear power plant. However, due to the lack of oxide-based passivation and selective dissolution of alloy elements, the corrosion of structural materials arises safety and maintenance concerns. 1
