| Abstract Scope |
Niobium Alloy C-103 (Nb-10Hf-1Ti wt%) is the most common Nb alloy that is used in many high temperature applications, e.g., advanced propulsion systems. However, its low and high temperature strength levels are relatively low, compared to advanced Nb alloys. Vanadium (V) is a strong solid solution strengthening element in Nb. However, there has not been any systematic study of the effects of V on the mechanical properties of the C103 Nb alloy. In this work, the effects of V alloying (up to 20 wt.%), during spark plasma sintering of the C103 alloy, and its effects on microstructure, strength, ductility and fracture toughness, are presented. Alloys with different oxygen levels were made to explore the synergistic effects of vanadium and oxygen. An increase in V increased the strength levels and decreased ductility and fracture toughness. The strengthening and fracture mechanisms are discussed, and pathways for increasing ductility and toughness are clarified |
