本文研究了不同多次时效工艺技术对NbTi—25Ta/Cu多芯复合线临界电流密度的影响。实验结果表明,所研究的材料获得了高性能,4.2K、5T与1.87K、10T下的Jc分别达到了2.71×10~5A/cm~2(六次时效的)和1.68×10~5A/cm~2(四次时效的)。这些性能在国际相同组份超导材料中居领先地位。
In this paper, the effects of different multiple aging treatments on the critical current density of NbTi-25Ta / Cu multi-core composite wires were studied. The experimental results show that the materials studied have high performance, and the Jc at 4.2K, 5T and 1.87K and 10T respectively reach 2.71 × 10 -5 A / cm 2 (six times aging) and 1.68 × 10 -5 A / cm ~ 2 (four aging). These properties in the international same-component superconducting materials in the lead.
