Continuous bending-drawing process to manufacture the ultrafine copper wire with excellent electrical and mechanical properties
TL;DR: In this paper, a continuous bending-drawing process to manufacture ultrafine electric wire is proposed, which is capable of manufacturing ultrafine wire with excellent electrical and mechanical properties, by controlling the microstructure and grain orientations affected by the loading directions during drawing and bending.
