The material was studied after its exposure to molten mixture 60 mol. % LiF + 40 mol. % NaF at temperature 993 and 1013K. The exposition was carried out in a quasidynamic regime, which simulates coolant (the mixture of salts) natural circulation conditions in components. The structure of the alloy was studied by SEM. Severe corrosion damage was observed in the surface layer, which thickness was about 300 μm.
