摘　　要：系统研究了高强高导铜材料的强化机理和制造技术,提出了“增强强化相”(提高弥散强化相强度)、“超饱和固溶”(提高基体中弥散强化相浓度)、“柔性包裹铜晶界”(提高材料高温强度等新型强化机制)的创新思路,为同时具有高强度和高导电、高导热的铜基材料成份和显微组织设计提供了理论基础,并在材料学科权威期刊发表相关论文20余篇。发展出高强高导铜的大吨位、连续化、绿色制造技术,实现了全真空大吨位铬锆铜材料的规模生产,具有工艺简单、流程短,所制备的材料结构全致密、显微组织无偏析、性能均匀一致等优点。高强高导铜材料生产项目技术评估价为1500万元,采用混合实施模式(支付西安交通大学300万元现金,发明人技术入股1200万元),与陕煤集团合作成立了发明人技术入股、骨干团队现金参股的混合所有制企业。建成了一期千吨量级生产线,产品在多个国家龙头企业获得规模应用,并即将建设万吨量级生产线,对于国家高铁、芯片、发动机等多个领域关键材料的升级换代具有重要意义。The research conducted focused on the development of strengthening mechanism and manufacturing technique for copper-based materials with high-strength and high conductivity.These new mechanisms were proposed,namely the“strengthening second phase”to enhance the strength of the dispersion-strengthening phase,“super-saturated solid solution”to increase the concentration of the dispersion-strengthening phase in the matrix,and“flexible coating in copper grain boundaries”to improve the high temperature strength of these materials.These findings provide a theoretical foundation for the composition and microstructure design of high-strength and high-conductivity copper alloys.Over 20 relevant research papers on this topic were published in reputable journals.Furthermore,a continuous fabrication technique was developed for the scale green manufacture of high-strength and high-conductivity copper materials.This manufacturing process is characterized by its simplicity,with short duration,and the resulting copper materials exhibiting a fully compact structure,with no segregation in microstructure,and high performance uniformity.The implementation of this project was assessed to be worth 15 million RMB,and a new company was established with an investment structure consisting of 3 million RMB cash payment to Xi’an Jiaotong University and a 12 million RMB investment owned by the inventor.A mixed ownership enterprise was formed in collaboration with Shaanxi Coal Group,and the first production line of 1000 tons has already been completed.The result products have been utilized by a number of national leading enterprises.Additionally,plans are underway to construct a 10000 ton production line in the near future.These achievements have great significance implications for the advancement of key materials in various fields such as national high-speed rail,chips,and engines.
