| Abstract Scope |
Due to their higher melting points and lower density compared to other refractory metals, Nb-based alloys have emerged as prominent in high-temperature applications. In this work, the feasibility of making the Nb-based alloy C103 (Nb-10Hf-1Ti, wt%) by the Electric Field Activated Sintering (EFAS) technique has been investigated. High purity Nb, Hf, and Ti powders were blended and sintered in an argon atmosphere and by direct heating under pressure in a SPS unit. The densification behavior and microstructures were characterized to determine the extent of solid solution alloying and the elimination of porosity. The changes in the lattice parameters of Nb solid solution as well as the formation of compounds, as a function of sintering time were investigated. Mechanical properties such as tensile strength and fracture toughness have been investigated and correlated with the microstructure. The properties of the sintered alloys are also compared with those of commercially wrought Nb alloys. |
