摘要(Abstract)：

为适应700℃等级先进超超临界燃煤发电（700℃A-USC）机组严苛的服役环境，助力高效低碳燃煤发电技术的发展，高温合金拟被用于制造电站锅炉和汽轮机的高温构件。结合本国火电发展特点，美国、欧洲、日本、中国、印度等国家及地区先后提出并实施了具有各国特色的700℃技术研究计划。高温合金由于元素种类多、焊接难度大、产生焊接缺陷的倾向大，因此焊接技术和接头综合性能评价技术对高温构件的厂内制造、现场加工与修复以及服役安全性与完整性的影响重大。当前国内外700℃技术实际应用进展缓慢，主要原因是制造、连接、检测等技术障碍未完全解决。综述了国内外700℃技术的研究计划，并分析其发展前景，讨论了锅炉侧和汽轮机侧高温构件的选材现状，总结了当前高温合金焊接技术的现状与优缺点，分析了高温构件接头综合性能评价的关注重点，最后提出中国发展700℃技术的建议。
