## Description

- description: We are approaching to high mechanical strength of bronze processed
    Nb3Sn wire by internal matrix reinforcement using Cu-Sn-In ternary alloy. The
    In solute element remained homogeneously in the wire matrix after Nb3Sn synthesis,
    and it contributed to transforming (Cu, In) solid solutions. And (Cu, In) solid
    solution acted as the protective material of Nb3Sn phase and contributed to improving
    the mechanical strength of the Nb3Sn wire. In this study, we investigated the
    Hot Isostatic Press (HIP) treatment on the further mechanical strength improvement
    of internal matrix reinforced Nb3Sn wire. Tensile stress and strain sensitivities
    of transport critical current (Ic) property were enhanced by HIP processing because
    many micro-sized vacancies, which were the originpointsofthefatigueonthe(Cu,In)matrix,were
    removed.  We found the HIP treatment contributes to mechanical strength enhancement
    of the internal matrix reinforced Nb3Sn wire.
