摘　　要：首先回顾了铁基超导体的一些基本特性和大角晶界的弱连接效应,探讨了制备高性能铁基超导线带材的物理基础。然后从制备工艺、包套材料、晶界结构、化学掺杂等方面系统地总结了铁基超导线带材的发展历程,同时简要介绍了目前国内外的一些最新进展。最后对铁基超导线带材的应用前景进行了展望。Some of the basic characteristics, especially the weak link effect, of the iron based superconductors were reviewed at first. Then the fabrication process for iron-based superconducting wires ＆ tapes, sheath mate- rials, grain boundary structure and chemical doping were summarized, and some recent progress involving high critical current density were introduced briefly. Finally, a perspective and future development of iron-based su- perconducting wires ＆ tapes were also given.
