| Abstract Scope |
Immiscible metallic nano-composites exhibit promising properties like enhanced strength, thermal conductivity, and damage tolerance. However, the inherent miscibility gap in the liquid phase precludes casting and forging, necessitating solid-state processing methods such as high-energy mixing or powder sintering, which offer limited control over microstructure and associated properties. We employ additive manufacturing (AM) to synthesize immiscible steel-copper composites via on-the-fly alloying in direct energy deposition (DED). DED is employed for its capability to rapidly explore the effect of copper content. We established a processing map, identifying fully-dense regions. Microstructures were characterized using scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD), focusing on phases and grain sizes present. Mechanical properties were evaluated, with emphasis on strength and ductility. Our results link the unique microstructure of these novel materials to their properties. |
