| Abstract Scope |
HT9 Ferritic/Martensite (F/M) steels with high chromium content (8-12%) are promising candidates as a structural material for the sodium-cooled nuclear reactors due to their better corrosion resistance, thermal properties, and swelling resistance compared to other austenite steels. By applying a magnetic field during the tempering process, alterations to the formation of carbides and dislocation densities result in changes to the mechanical properties and irradiation resistance. This study will investigate the microstructure and mechanical properties of HT9 tempered between 600-750°C under the influence of external magnetic field ranging from 0-9 Telsa. Compression, tensile, Vickers microhardness and micropillar testing experiments were conducted to reveal their mechanical behavior. The microstructure was analyzed using XRD, TEM and EBSD techniques. The combined effects of magnetic field during tempering to microstructure and mechanical properties will be discussed. |
