| Abstract Scope |
Niobium's unique combination of high melting point, low density, and excellent strength made it a prime candidate for re-entry vehicle and high-temperature applications during the 1960s. This presentation explores the mechanical performance of various historical niobium alloys, including C-103 (Nb-10Hf-1Ti [wt%]), FS-85 (Nb-28 Ta-10W-1Zr), Cb-752 (Nb-10W-2.5Zr), and WC-3009 (Nb-30Hf-9W-1Zr-0.2C). The research focuses on high-temperature uniaxial tension testing of these alloys in both their original wrought form and fabricated using Laser Powder Bed Fusion (L-PBF) additive manufacturing. Testing was conducted in a high-vacuum environment to minimize contamination from interstitial elements. This comparison allows us to understand the impact of L-PBF microstructure on the strength of these materials. The overall objective is to evaluate a broad range of historical niobium alloys to determine if any retain potential for future aerospace applications, particularly those requiring exceptional strength at high temperatures. |
