Research hotspots evolution and frontier trends in high-strength high-conductivity Cu-Cr alloys
【摘要】 铜铬系合金因其“高导电-高强度”的独特组合性能,兼具高温抗氧化和耐腐蚀能力,已成为电力传输、航空航天散热系统及核电站耐辐射部件等极端工况领域的关键候选材料之一。采用CiteSpace文献计量方法,对CNKI数据库中561篇铜铬系合金相关研究文献的作者、机构和关键词等展开定量与可视化知识图谱分析。结果表明,我国在该领域研究积累深厚,合作网络呈“小团体聚集”特征。研究热点聚焦热处理/塑性变形工艺、力学-电导协同优化及微观结构-性能关系,其中高强高导性能方面最具研究价值。为解决强度-导电率矛盾,时效热处理与微合金化成为主要策略,结合快速凝固、剧烈塑性变形等技术,实现Cr、Cu5Zr等纳米析出相的跨尺度调控。突现词分析显示,近期研究前沿以抗拉强度、上引连铸及析出相为代表,短流程制备工艺因成本与性能优势成为重点。未来研究将向“双90”或更高性能目标迈进,以满足航空航天、高铁接触线等高端需求。
【Abstract】 Cu-Cr alloys have emerged as critical candidate materials for extreme service conditions—including power transmission, aerospace thermal management systems, and radiation-resistant components in nuclear power plants—due to their unique combination of high electrical conductivity and high strength, coupled with excellent high-temperature oxidation resistance and corrosion resistance. Using CiteSpace bibliometric methods, a quantitative and visual knowledge mapping analysis was conducted on 561 research papers related to copper-chromium alloys in the CNKI database, examining authors, institutions, and keywords. The results reveal that China has developed substantial research depth in this field, with collaborative networks exhibiting “small group clustering” characteristics. Research hotspots primarily focus on heat treatment/plastic deformation processes, mechanical-electrical property synergy optimization, and microstructure-property relationships, with high-strength, high-conductivity performance demonstrating the most significant research value. To resolve the strength-conductivity trade-off, aging heat treatment and microalloying have emerged as primary strategies. When coupled with rapid solidification and severe plastic deformation technologies, these approaches enable cross-scale regulation of nano-precipitates such as Cr and Cu5Zr. Burst term analysis reveals that recent research frontiers are dominated by tensile strength, upcasting continuous casting, and precipitate phases, with short-process preparation technologies gaining prominence due to their cost-performance advantages. Future studies will pursue “dual-90”(90% IACS conductivity with 900 MPa strength) or higher performance benchmarks to meet demanding applications in aerospace and high-speed rail contact wires.
