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.

我们将研究用市售含镁和/或硅的铝合金薄片，通过Jelly-Roll技术制造Nb3Al多芯超导线材的可行性。无氧高导电性铜将作为稳定剂纳入导体设计。将测试低温挤压的传统线材制造工艺。将测量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。其目的是开发一种性能超过现有材料的超导导线。
