Microstructure evolution and deuterium permeation behavior of CLF-1 steel under Li4SiO4 tritium breeder corrosion cycles
Source abstract
Abstract
The effect of corrosion cycles on the microstructural evolution and deuterium permeation behavior of CLF-1 steel in Li 4SiO 4 are systematically analyzed. The study reveals the progressive development of multi-layered structures comprising alternating Li-Fe-O phases and Cr-rich layers with prolonged corrosion. XRD, SEM, spectroscopy, and thermodynamic analyses attribute the formation of sparse Li-Fe-O structures (such as Li 2Fe 3O 5, Li 5FeO 4, and LiFeO 2) is the dissolution of the FeCr 2O 4 by lithium. In contrast, the Cr 2O 3 phase in the Cr-rich layer remains nearly insoluble in lithium. Finally, the tritium-blocking performance of the multiple Cr-rich layer improves with corrosion were found.
