| Abstract Scope |
This study investigates the processing and characterization of an Aluminum-Boron Nitride Nanoparticle (Al-BNNP) composite fabricated via Friction Stir Processing (FSP). The novel design of the FSP process, including the effect of tool geometry and the dispersion challenges of high-strength Boron Nitride Nanoparticles (BNNPs) in solid-state is investigated. Microstructural variations across different weld zones are examined using electron back scattered diffraction and transmission electron microscopy, focusing on the effect of BNNPs on grain morphology and refinement. The study also explores the radiation shielding properties of the composite, particularly the neutron capture mechanism of the 10B isotope in BNNPs, demonstrating the multifunctional nature of the material. Additionally, Atom Probe Tomography (APT) reveals the transmutation of boron to lithium subjected to fast moving neutron irradiation exposure. The results highlight the potential of Al-BNNP composites for advanced applications such as radiation shielding and multifunctional material in space exploration. |
