“…The microstructure, which encompasses the overall properties of grains and includes their morphology, size, and type of boundaries, plays a crucial role in determining the behaviors and properties of a given metallic material [1]. Currently, the majority of metallic materials are prepared via either methods based on bulk casting [2][3][4] or techniques based on the processing of metallic powders (e.g., mechanical alloying [5,6], cold and hot sintering [7,8], selective laser sintering (SLS) [9,10], powder bed fusion (PBF) methods [11,12], and more). In order to enhance the microstructures of cast/sintered workpieces, deformation processing can be employed as an additional production step.…”

Copper generally exhibits high electrical conductivity but has poor mechanical properties. Although alloying can improve the latter characteristic, it usually leads to a decrease in electrical conductivity. To address this issue, a promising approach is to enhance the performance of copper while maintaining high electrical conductivity through optimized deformation processing, which refines the structure and increases mechanical properties. This paper focuses on assessing the effects of rotary swaging, a form of deformation processing, on microstructures and substructures of electroconductive copper bars. This analysis is complemented by experimental measurements of electrical conductivity. The results demonstrate that gradual swaging, i.e., applying different swaging ratios, influences the structure-forming processes and consequently affects the electrical conductivity. The increased electrical conductivity was found to be associated with the elongation of the grains in the direction of the electron movement.
