Abstract Scope Metal additive manufacturing (AM) presents unprecedented opportunities for microstructural engineering and material innovation by leveraging the non-equilibrium conditions intrinsic to the process. This talk outlines three strategies for harnessing the unique thermal and dynamic environments of AM to develop advanced materials tailored for specific applications. First, we demonstrate how manipulating phase stability in high-entropy alloys (HEAs) refines grain structure through the formation of metastable phases during solidification. Next, we investigate alloy amalgamation in AM to create hybrid titanium alloys with tailored properties. This approach utilizes rapid solidification and limited diffusion to achieve distinct phase coexistence, unattainable through conventional methods. Finally, we explore the potential of natural mixing effects in AM, driven by Marangoni convection, to process immiscible systems like Fe-Mg, thereby enabling tunable degradation kinetics for biomedical implants. Together, these studies highlight the transformative potential of AM in controlling microstructural evolution and expanding the material design landscape.
