Abstract:With the rapid development of aerospace, microelectronics, rail transit, communication and other industries, higher requirements have been put forward for the performance of copper alloys with high strength and high electrical conductivity. This paper reviews the micro-alloying principle, thermo-mechanical processing, phase transformation and the relationship of microstructure and properties of the various typical copper alloys with high strength and high electrical conductivity. The distribution of alloying elements in the alloy and their effect on the precipitation behavior, phase transition sequence and microstructure evolution of the alloys in service were stated. The main problems and relevant solutions of the copper alloys with high strength and high electrical conductivity were recommended.
Key words: copper alloy; high strength; high electrical conductivity; alloying; phase transformation
