Abstract Scope |
HT9 Ferritic/Martensite (F/M) steels with high chromium content (8-12%) are promising candidates as cladding and structural materials for the next generation of nuclear reactors due to their excellent corrosion resistance, thermal properties, and better swelling resistance under irradiation compared to austenitic steels. The grain and sub-grain boundaries including laths and precipitates such as carbides play a significant role in mechanical properties and irradiation resistance. Engineering these microstructural features can improved mechanical properties and irradiation resistance further. This study will investigate the microstructure and mechanical properties of HT9 steels systematically tempered between 650oC-750oC under the influence of external magnetic field ranging from 0 to 9 Tesla. Using optical microscope, SAXS, XRD, SEM and TEM testing techniques, the morphology and size of carbides, martensite plates as a function of magnetic field and the resulting effects on mechanical properties will be discussed. |
