Abstract Scope |
Virtually all alloy design strategies that exist today consider solid-state transformations (strain-induced or diffusive). In this presentation, we introduce two alloy design strategies that leverage reactions happening in the solidifying liquid. First, liquid-liquid phase separation, a traditionally deleterious phenomenon in castings, which allows to synthesize scalable metallic composites in AM. Second, icosahedral short range order-induced nucleation, which leverages local ordering in undercooled liquids to stimulate the nucleation of twin-related grain clusters. Emphasis will be placed on the fundamental solidification mechanisms, microstructure development through multi-scale characterization, and framing transformative design guidelines that leverage these phenomena for the design of novel printable alloys. |
