## Description

- 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.
