| Abstract Scope |
This study presents a unified additive manufacturing (AM)-based strategy for tailoring compositional gradients in multi-material aluminum systems to overcome the limitations of conventional multi-material integration. An AM-based combinatorial framework was employed to identify effective interfacial chemistries that enhance bonding and thermal performance between dissimilar aluminum components. In parallel, directed energy deposition (DED) was used to fabricate compositionally graded structures by continuously varying the feedstock composition, enabling systematic control of local microstructure and properties. By integrating interfacial design with gradient material architectures, this study demonstrates a scalable pathway for tailoring performance in aluminum-based hybrid systems. The approach provides a general platform for designing next-generation lightweight structures with enhanced structural and functional properties. |
