dc.description.abstractIn this paper, the change of mechanical and structural properties of micro-alloyed copper during the cold rolling and annealing process was monitored. Melting and casting of micro-alloyed copper was carried out in an electrical resistance furnace, with the "up-cast" casting process. The melted and chemically homogenized material was further subjected to the extrusion process, after which cold plastic deformation was performed with deformation degrees of 10, 30, 50 and 75%. Annealing of cold deformed samples was performed at 450°C for 35 min. The cooling of the samples was done in water with alcohol. After each stage of the experiment, the values of hardness, tensile strength and relative elongation were measured. The results showed that the values of hardness and tensile strength of unannealed samples increase with the increase in the deformation degree, while the relative elongation decreases. Deformation degree also affected the final grain size after the annealing process. At the highest deformation degree, the finest grains were obtained.
