为了制造实现低箔重量和体积的大口径、高场磁体，需要高强度的复合超导线材。氧化铝-铜强化（Nb、Ti）/sub 3/Sn导线，含量为30vol. %研制了一种用管式法制备的Al 2 O3-Cu合金，并对其临界电流密度、力学性能、横向压应力效应及相关性能进行了测试。结果发现，增强的（Nb，Ti）/sub 3/Sn线材具有高的横向压缩应力耐受性，例如在60 MPa下仅降低3%，这是Cu基体线材在I/sub c//I/sub c 0/中的1/3，并且在0和200 MPa之间的I/sub c/中具有可逆性。利用新研制的增强型-（Nb，Ti）/sub 3/Sn超导线材，在不久的将来将有可能制造出重量轻、大口径、高场、紧凑的超导磁体。
In order to fabricate a large-bore, high-field magnet which achieves a low foil weight and volume, a high strength compound superconducting wire is required. The alumina-copper strengthened (Nb,Ti)/sub 3/Sn wire which contained 30 vol.% alumina-Cu alloy fabricated by using the tube process has been developed and tested for critical current density, mechanical properties, transverse compressive stress effects and related properties. As a result, it was found that the reinforced (Nb,Ti)/sub 3/Sn wire had high transverse compressive stress tolerance, for example only 3% decrease which was 1/3 of the Cu matrix wire in I/sub c//I/sub c0/ at 60 MPa and reversibility in I/sub c/ between 0 and 200 MPa. Using the newly developed reinforced-(Nb,Ti)/sub 3/Sn wire, it will be possible to fabricate a lightweight, large-bore, high-field and compact superconducting magnet in the near future.
