| Abstract Scope |
Ferritic/Martensite (F/M) steels with high chromium content (8-12%) are of great interest as a candidate cladding material for fast nuclear reactors due to their good thermal properties, corrosion resistance, and performance under irradiation including better swelling resistance compared to austenitic steels. In theory, HT9’s mechanical properties and irradiation resistance could be further improved if the microstructural features including laths and carbides can be tailored. In this study, HT9 steels are systematically tempered between 650-750oC under the influence of external magnetic field (0-9T) and the changes to their microstructure and material properties are investigated. The effects of magnetic field tempering on the morphology and size of carbides, martensite plates and resulting effects on mechanical properties will be discussed. |
