| Abstract Scope |
Rapid solidification of laser-based metal additive manufacturing (AM) enables processing of unconventional alloys with unique metastable microstructures that are impractical to achieve conventionally. A number of emerging alloys have been explored with AM, such as refractory metals, high entropy alloys, and metallic glasses. This latter group of materials have been shown to develop amorphous structures when rapidly solidified via metal AM, reinvigorating the possibility of manufacturing near-net-shape bulk metallic glass parts. We implement a high-throughput alloy processing and characterization methodology to rapidly evaluate structure-property evolution across the Ni-Nb binary system, which exhibits a wide glass-forming compositional range. We also present the results of Molecular Dynamics simulations that provide insights into material properties across the range of compositions. This work serves as preliminary results of high-throughput experimental and computational tools that have been developed to accelerate AM materials development.
