| Abstract Scope |
Investment casting of high-strength aluminum alloys AA7075, AA6061, and AA2024 is often hindered by solidification defects such as shrinkage and hot cracking. This study explores the addition of nanoparticles to these alloys to mitigate such defects. Nanoparticles act as potent nucleation sites, refining microstructure morphology and enhancing liquid metal fluidity, resulting in improved mold filling. Experimental results demonstrate that nanoparticle-enhanced alloys exhibit significantly reduced solidification defects and better fluidity compared to conventional commercial alloys A383 and A356. The improved casting quality suggests that nanoparticle incorporation offers a promising approach to overcome the inherent solidification challenges of these alloys, enabling their broader use in demanding aerospace and automotive applications. |
