## Description

- description: This paper reviews the Pb- and Cd-free NbTi/Nb3Sn superconducting joint
    technology and the related technologies. The key to the Pb-free joining process
    is the use of a high-temperature tolerable Nb superconducting alloy as an intermediate
    material, which enables metallic bonding between the Nb3Sn wire and the Nb superconducting
    alloy intermediate material through a chemical reaction, and between the NbTi
    wire and the Nb superconducting alloy intermediate material by pressure welding.
    Consequently, the NbTi/Nb3Sn superconducting joint is realized. This novel technology
    is expected to be used in the world’s first Pb-free, environmentally friendly
    NMR superconducting magnets.
