摘　　要：现代航空航天和能源工业的快速发展,对高温结构材料的服役性能要求日益提高。化学式为AB2型的Laves相金属间化合物因其高熔点、出色的高温强度和抗氧化性能而备受关注,并被视为新一代高温结构中有应用前景的候选材料之一。本文基于CiteSpace文献计量软件首次对2003~2023年WOS数据库中2080篇Laves相研究相关论文进行了作者、国家、机构和关键词等题录的可视化回顾和定量分析。结果表明:Laves相研究的合作关系较弱,未来需跨机构和跨区域合作提升效果。中国、德国、日本和美国等稳固占据研究力网络合作路径上的关键位置。具有高发文频次和高中心性的中科院金属研究所等5个机构是相关最顶尖和贡献程度最大的科研机构。Laves相研究的热点主题包括电子结构、G115钢、Inconel 718合金等,研究方向集中在改善Laves相基合金的脆性和重新评估Laves相析出物对新型耐热钢、镍基高温合金和难熔高熵合金的热稳定性和寿命的影响作用及协同强化效应。这项研究为深入了解Laves相研究现状和发展动向提供了系统而有价值的启示和参考信息。The rapid development of modern aerospace and energy industries has led to increasingly higher demands for the service performance of high⁃temperature structural materials.The Laves phase with the chemical formula AB2 type has attracted attention due to its high melting point,excellent high⁃temperature strength,and oxidation resistance,making it considered as one of the promising candidate materials for the new generation of high⁃temperature structures.This study based on CiteSpace literature analysis software,provides a visual retrospective and quantitative analysis of the bibliography including authors,countries,institutions and keywords of 2080 related research papers from the WOS database from 2003 to 2023.The results show that the collaborative relationships in Laves phase research are relatively weak,and there is a need for cross⁃institutional and cross⁃regional collaborations in order to enhance effectiveness.Countries such as China,Germany,Japan and America consistently occupy key positions in the research power network cooperation paths.Five institutions including the Institute of Metal Research of the Chinese Academy of Sciences,which have high publication frequencies and centrality,are among the top research institutions in terms of relevance and contribution levels.Hot topics in Laves phase research include electronic structures,G115 steels,Inconel 718 nickel⁃based alloys,etc.,with research directions focusing on improving the brittleness of high⁃temperature alloys and reevaluating the impact of Laves phase precipitates on the thermal stability and lifespan of new heat⁃resistant steels,nickel⁃based high⁃temperature alloys,and refractory high⁃entropy alloys,as well as synergistic strengthening effects.This study provides valuable insights and reference information for a systematic understanding of the current status and development trends in Laves phase research.
