Abstract (english)
Irreplaceability of copper, as an electrical conductor, makes it the most important non-ferrous metal in application. The most frequently used methods of producing the copper conductors involves continuous casting of the copper wire, subsequent cold drawing deformation and heat treatment processes to improve copper mechanical and electrical properties. In this paper the research was performed on copper wire produced by continuous casting. During production various structural changes and changes in mechanical properties occur. To investigate those changes and to clarify their influence on final product, structure and hardness were recorded and measured in all stages of production. While macrostructure and microstructure were observed by light microscopy, the hardness was measured using Vickers hardness testing method. The results indicate that the initial coarse-grained structure in as-cast condition, brakes down into a fine- grained structure during reduction. Those fine grains are orientated in the direction of cold drawing during plastic deformation. There is an increase in the hardness. The purpose of heat treatment is to achieve better conductivity while maintaining good mechanical properties. The results of microstructure analysis indicate the presence of twin crystals in the structure of the final product
