摘    要:

涂层超导材料是一种有着广泛应用前景和巨大潜在商业价值的高温超导材料之一。随着人们对高性能涂层超导带材研究的不断深入,基带材料作为涂层超导材料YBa2Cu3O7?x(YBCO)多层结构中重要的组成部分也呈现出新的科研成果,基底的研究在金属种类选择上和再结晶理论的研究方面都取得明显的进展。总结目前几种重要的金属及其合金基底,从材料的制备手段,织构形成的特点和性能,存在的优缺点以及未来的发展趋势等方面介绍了涂层导体中金属基带的研究现状。

Abstract: Coated conductor (CCs) with large potential commercial value, which is a promising candidate for wide HTS materials application, has been systematically studied for many years. Though choosing and combining varied metal materials, the metal substrate as the essential part in YBa2Cu3O7-x (YBCO) multi-layers structure has reached a series of the latest achievements on both fabrication method and the understanding of recrystallization theory. The development of different kinds of alloy substrates used in either rolling-assistant biaxially textured substrate technique or ion beam assistant deposition method was reviewed. Furthermore, from the view of cost-effect, several popular substrates were proposed.
