| 摘 要： | MgB_2线带材的加工经历了近15年的研究与发展,生产出的线带材可以在制冷机、较低磁场下使用,另外生产MgB_2线带材的原材料相对低廉,应用前景十分广泛。本文从MgB_2传统线带材加工和后续工艺方法的优化出发,概述了MgB_2线带材研究的进展,详细介绍了内部镁扩散法,即用中心镁棒代替传统镁粉,使用铜镍材料为包套,钽或铌为阻隔层并与镁之间填充硼粉,热处理后得到致密的MgB_2相。论述了未来MgB_2线带材加工的研究重点。

| Abstract: | The MgB2 wires and tapes have been well developeded during the past 15 years. MgB2 can be used in liquid hydrogen and low magnetic field, which has broad applicability in the future due to its cheap raw material. In this paper we review the traditional processing of MgB2 wires and set the stage for further. The method of internal magnesium diffusion is introduced in detail. A pure magnesium rod was placed at the center of copper shealth and niobium or tantalum barrier layer, and the space between magnesium rod and barrier layer was filled with boron powder. We can get the high density MgB2 layer after heat treatment. Finally, we discussed the key point of fabricating MgB2 tapes and wires in the future. |
