| Abstract Scope |
Ferritic/Martensitic steels are one of the most promising candidates for structural and cladding applications in advanced reactors due to their thermal properties and resistance to swelling. However, F/M steels suffer from radiation embrittlement at low temperatures, creep at elevated temperatures and swelling at very high doses at intermediate temperature. Application of magnetic field during tempering has the potential to address these challenges by engineering the microstructure including the size and morphology of carbides. In this talk, we will present our recent findings on the effects of magnetic field on the microstructure and mechanical properties under magnetic field strength of up to 9T. Mechanical tests show that the magnetic heat-treated specimens show increased yield strength compared to conventional heat-treated specimens. 1.5 MeV proton irradiations were performed at 300C to a dose of 0.25 dpa. Initial investigations using micro pillar compression tests indicate softening presumably due to stability of carbide precipitates. |
