Abstract

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 1 000 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 10 000 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.
