The principle of wire drawing is based on the reduction of the section of the cylindrical pieces of the materials according to their plasticity by the forced passage of the latter in a sector. The aim of this work is to study the influence of the deformation level resulting from the wire drawing process at ENICAB of Biskra on the evolution of the microstructure, the texture and the mechanical properties of the copper wire destined for the transmission of electrical energy.
The characterization methods used in this study to identify the evolution of microstructure and texture and also the mechanical properties of deformed wires are: electrons backscattered Diffraction (EBSD), X-ray diffraction, optical microscopy (MO) and electronics microscopy (MEB), the microhardness and the tensile test. Structural analysis by EBSD shows that the wire strongly deformed by wire drawing consists of two fibers <111> // DN (majority // to the drawing axis) and <001> // DN (minority // to the wire drawing axis) and also a decrease in the size of the grains which becomes more homogeneous after the elevation of the level of deformation. The study of the mechanical properties shows a significant increase in the hardness and the mechanical resistance as a function of the deformation [1-3].
