研究了基体中添加钛对复合加工 Nb3Sn 的超导性能和冶金方面的影响。发现添加到基体中的钛很容易扩散到 Nb3Sn 层中。基体中添加少量钛可显着提高 Nb3Sn 层的生长速率和高磁场中的临界电流密度 Jc。 Nb/Cu-7 在 16 T 时获得了超过 1×105 A/cm2 的 Jc（Nb3Sn 层）。 % Sn-0.35 at。 ％Ti复合丝在750°C反应100小时。实际上，将钛添加到基体中可能比将钛添加到芯中更有希望。
The effects of a titanium addition to the matrix on the superconducting properties and the metallurgical aspects of the composite‐processed Nb3Sn have been studied. The titanium added to the matrix is found to diffuse readily into the Nb3Sn layer. The small amount of the titanium addition to the matrix significantly increases the growth rate and the critical current density Jc in high magnetic fields of the Nb3Sn layer. A Jc(Nb3Sn layer) of over 1×105 A/cm2 has been obtained at 16 T for the Nb/Cu‐7 at. % Sn‐0.35 at. % Ti composite wire reacted at 750 °C for 100 h. The titanium addition to the matrix may be practically more promising than the titanium addition to the core.
