| Abstract Scope |
Innovative lightweight alloys are crucial for manufacturing cost-effective aerospace structures for space exploration. Aluminum alloys, particularly AA5356, are widely used as fillers but imply high fabrication costs due to alloying elements and post-welding treatments. To overcome these limitations, this study explores the development of aluminum-magnesium-based fillers reinforced with niobium diboride (NbB₂) nanoparticles. NbB₂ particles improve mechanical properties, providing enhanced strength, hardness, and higher service temperatures compared to unreinforced fillers. Nanoparticles were produced via high-energy ball milling and incorporated into Al-Mg alloys through stir casting, creating a cost-effective and reproducible fabrication process. Preliminary tensile (140MPa) and hardness (315HV) tests showed up to a 40% improvement in reinforced welds. Thermal analysis revealed a melting point increase of 5% (661.35°C) compared to unreinforced fillers. These findings highlight the potential of nanoparticle-reinforced fillers to enhance weld performance, ensuring reliable components for extreme conditions. Future work includes electrical resistivity analysis and finite element modeling. |
