| Abstract Scope |
Niobium-based refractory alloys are gaining attention for high-temperature applications particularly, in space and hypersonic systems. Additive manufacturing (AM) offers key advantages for these materials, allowing complex geometries and enabling the use of alloys that are difficult to process conventionally.
This collaborative study by TANIOBIS GmbH and Alloyed Ltd. focuses on the development and AM processing of three commercially available niobium-based alloys: C-103, Cb-752, and FS-85. While C-103 is widely used in aerospace, Cb-752 and FS-85 are less studied. In this work, they are specifically evaluated and optimized for use in AM to assess their suitability for high-temperature applications. We advanced these alloy powders from laboratory trials to scaled demonstrator components through a structured TRL progression. The study highlights the feasibility of AM for both conventional and repurposed niobium alloys and emphasizes the role of powder development, process tuning, and mechanical validation in enabling next-generation refractory components. |
