| Abstract Scope |
Aluminum composites reinforced by B4C particles possess large thermal neutron absorption cross-section owing to 10B isotope, which are utilized for casks and storage pools for the containment of spent-nuclear fuels. Through the powder metallurgy methods, the composites are fabricated by hot pressing (HP) or spark plasma sintering (SPS) that has advantages in achieving dense microstructures compared to cold pressing and sintering. The HP takes a long time due to the indirect heating resulting in grain coarsening and property differences in a sintered body, while homogeneous microstructures can be obtained in the SPS by joule heating. It is necessary to understand differences in microstructures and properties of the composites sintered by each method to realize the property-tailored materials. In this study, the microstructures and mechanical properties of the B4C/Al composites fabricated by the HP and SPS are systematically investigated and compared. |
