| Abstract Scope |
Ferritic/Martensitic (F/M) steels are one of the most promising candidates for structural and cladding applications in advanced reactors due to their better thermal properties and resistance to swelling. However, F/M steels suffer from radiation embrittlement at low temperatures (<400°C), creep at elevated temperatures (>500°C) and swelling at very high irradiation doses at intermediate temperature ranges. Tempering under external magnetic field has potentials to address these challenges by engineering the microstructure including the size and morphology of carbides. In this study, we will present an overview of magnetic field effects during tempering followed by our recent findings showing the effects of external magnetic field on the microstructure and mechanical properties as a function of magnetic field strength of up to 9T. The specimens tempered with and without external magnetic field are subjected to light and heavy ion irradiations and characterized using electron microscopy-based techniques together with micromechanical testing on selected alloys. |
