| Abstract Scope |
Nb3Sn superconductors are the leading option for next-generation particle accelerator magnets. Wire manufacturing involves heat treatment for a diffusion reaction to occur. Additions of Hf to the Nb precursor alloys assist in maintaining finer grain sizes, which result in increased superconductor performance. However, increased demand and reliance on constrained resources such as Hf poses sustainability concerns for future particle accelerator projects, i.e. Future Circular Collider and development of lightweight RHEAs. To identify cost effective alternatives, series of binary Nb-X alloys, including X=Ti, Zr, Hf, V, Ta, Mo, W, and Re, were fabricated and cold rolled to observe effects of composition and deformation energy on recrystallization and grain growth processes. The samples were heat treated in a high temperature furnace, with resulting microstructure being characterized by EBSD and EDS. Thermomechanical processability of alloys was assessed as well, including work hardening behavior, flow stress, and hardness values. |
