英文摘要	High strength and high electrical conductivity (EC) are the key performance for Cu wire. However, the trade-off relation between the strength and the electrical conductivity limits the application of high-performance Cu wires. In the study, the simultaneous increase of strength and electrical conductivity was found in the oxygen-free Cu wire (OFCW) manufactured by cold-drawing process. The results show that the dislocation, texture and grain are three main factors influencing the strength and electrical conductivity of the cold-drawing OFCWs. Moreover, the contribution of microstructures to strength and electrical conductivity was calculated quantitatively. Three strengthening mechanisms including dislocation, grain boundary and < 111 > texture strengthening are considered to be the main factors that strengthen the colddrawing OFCWs. Besides, the elongated grains and the dislocation recovery are responsible for the increase of electrical conductivity. Finally, the thin-long grains are revealed to be the key factor leading to the synchronous increase of strength and electrical conductivity. (C) 2021 Elsevier B.V. All rights reserved.
