Nb3Al Superconducting Wire Using an Al-Alloy/Nb Jelly-Roll Processing Technique

通过果冻卷技术制造Nb3Al多丝超导线的可行性将进行研究，该技术使用市售的含有Mg和/或Si的铝合金片。无氧高导电性铜将作为稳定剂纳入导体设计中。对传统的低温挤压线材加工工艺进行了试验。将测量诸如Tc或Jc等新材料的超导性能。对超导复合材料的微观结构进行了研究和表征。其目的是开发一种超导导线，其性能超过目前的材料。

The feasibility of fabricating Nb3Al multifilamentary superconducting wires through a Jelly-Roll technique using commercially available aluminum alloy sheets, which contain Mg and/or Si, will be investigated. Oxygen free high conductivity copper will be incorporated into the conductor design as the stabilizer. The conventional wire fabricating processes with low temperature extrusion will be tested. The superconducting properties of the new materials such as Tc or Jc will be measured. The microstructures of the superconducting composite materials will be examined and characterized. The aim is to develop a superconducting wire with properties that exceed those of current materials.
