综述了用于锂自冷毯的低活化钒合金和 MHD 绝缘体涂层的最新进展。重点介绍了钒合金的研究进展，包括蠕变管制造技术、真空热蠕变与锂的比较、钒合金与锂之间的杂质迁移及其对机械性能的影响、氢和氢同位素的行为、低剂量辐照对焊接接头的影响以及先进钒合金的探索。钒合金的主要剩余问题是热蠕变和辐照蠕变、氦气对高温机械性能的影响以及辐射对低温断裂性能的影响。 Er2O3 与 Li 表现出良好的相容性，有望作为钒合金上的 MHD 绝缘体涂层。这种材料的涂层技术已取得重大进展。最近的努力集中在多层上。和原位涂层。在具有温度梯度的流动锂条件下进行测试对于定量检查涂层性能是必要的。 (c) 2007 Elsevier B.V. 保留所有权利。
Recent progress in the development of low activation vanadium alloys and MHD insulator coatings for a Li-self coolec blanket is reviewed. Research progress in vanadium alloys is highlighted by technology for fabricating creep tubes comparison of thermal creep in vacuum and Li, understanding impurity transfer between vanadium alloys and Li and its impact on mechanical properties, behavior of hydrogen and hydrogen isotopes, low dose irradiation effects on weld joints, and exploration for advanced vanadium alloys. Major remaining issues for vanadium alloys are thermal and irradiation creep, helium effects on high-temperature mechanical properties and radiation effects on low-temperature fracture properties. Er2O3 showed good compatibility with Li, and is promising as a MHD insulator coating on vanadium alloys. Significant progress in coating technology for this material has been made. Recent efforts are focused on multi-layer. and in-situ coatings. Tests under flowing lithium conditions with a temperature gradient are necessary for quantitative examination of coating performance.
