| Abstract Scope |
HT9 Ferritic/Martensite (F/M) steel (12Cr-1Mo) is a promising candidate as a structural material for the sodium-cooled nuclear reactors due to their corrosion resistance, thermal properties, and excellent void swelling resistance. The application of external magnetic field during tempering modifies carbide precipitation and microstructural evolution, thereby influencing mechanical properties and potentially irradiation resistance. This study will investigate the microstructure and mechanical properties of HT9 tempered between 600-700oC under the influence of external magnetic field ranging from 0-9 Telsa. These specimens were subjected to light ion irradiation and then micropillar testing experiments were conducted to reveal their mechanical behaviors before and after irradiation. The combined effects of magnetic field during tempering and irradiation to microstructure and mechanical properties will be discussed. |
