| Abstract Scope |
Refractory-based metallic glasses (RMGs) are desirable for applications involving extreme environments due to high strength, resistance to radiation and corrosion, and stability at high temperatures. RMG production requires rapid cooling of molten metal to bypass crystallization. Traditionally, processes such as melt spinning or suction casting are used, which result in small parts with limited application. Additive manufacturing through laser powder-bed fusion (LPBF) is a potential route to the production of bulk RMG parts. However, production of RMG feedstock can be quite challenging due to high melting temperature. In this study, TaNiCo RMG powder was produced through plasma melting and ultrasonic atomization (UA). The size-distribution, structure, and morphology of the resulting powders were analyzed. LPBF was performed, and the structure, properties, and high-temperature performance of the resulting parts were analyzed. TaNiCo RMGs produced through LPBF have the potential to be useful in extreme-environment applications including sustainable energy and space exploration. |
