高温超导带材经高压液氮浸泡后的性能研究

The properties of HTS tape after soaking in liquid nitrogen under high pressure

摘要:

高温超导带材一般运行于高压液氮的环境中,较大的压力可能会导致液氮渗透至带材内部。当带材由低温回温至室温时,汽化的液氮会对材料造成损伤。本文通过对不同工艺的高温超导带材进行高压液氮浸泡和回温处理,观测其性能的变化并研究相应的保护措施。

Abstract:

The high temperature superconductor (HTS) tape is generally working in the environment of liquid nitrogen under high pressure, liquid nitrogen maySpermeated into the interior of the tape resulting from the high pressure. The material would be damaged by the vaporized liquid nitrogen, when the HTS tape recovers from low temperature to room temperature. The HTS tapes with different manufacturing technologies are soaked in high pressure liquid nitrogen and rewarmed, the changes of properties and protective measures are studied in this paper.
