Description:

Our previous study on the addition of Hf–Ta to bronze-route Nb3Sn wires did not reveal a substantial effect on grain refinement. This lack of effect might be attributed to a smaller Sn diffusion driving force in the case of the bronze route. In this work, we study the Nb3Sn phase formation behavior in the case of a higher Sn diffusion driving force using tapes with a diffusion couple of Nb and high-Sn-content Sn–Cu alloy. Grain refinement in Hf-doped Nb 3 Sn wires was confirmed under a high Sn diffusion driving force.
