Abstract :

Iwill present the effect of wiredrawing on the mechanical and microstructural properties of industrial copper and aluminum wires. The regular orientation of the grains (texture) caused by external stresses during the cold wiredrawing process was observed. This texture causes a phenomenon of material consolidation. Unfortunately, the shaping by plastic deformation causes deterioration in mechanical and electrical properties of the material. To address this problem, we usually use annealing. Different heat treatments have been applied on these drawn wires, where the recrystallization reaction represented the main phenomenon during these heat treatments. Differential scanning calorimetry (DSC), X-ray diffraction, optical microscopy, transmission electron microscopy, scanning electron microscopy, micro-hardness measurements, tensile tests, and creep tests were used as techniques of characterization.
