“…This structure is fairly regular, which leads us to say that the crystallites are substantially isotropic, Figure 1a. And as prescribed by the literature [14][15]. Figure 1b shows the typical elongated aluminum grain structure noted in the artificially aged 6101 wires formed during prior deformation processes.…”

An investigation has been done to study the effect of heat treatment at low temperature on the development of mechanical and electrical properties of the industrially cold drawn aluminum alloy wires (6101). This aluminum alloy is used by the national company of electric cables of Biskra (ENICAB) for the transmission lines of electrical energy. The mechanical and electrical properties of the Al-Mg-Si alloys can be changed by heat treatment. Different technical procedures have been used In order to understand the complicated effect of aging on 6101 aluminum alloy; we have used the optical microscopy, hardness measurements and the electrical resistivity measurement. It was noted that the cold drawing of this aluminum alloy increase the microhardness which is produced by a high strain hardening of the material accompanied by a development of a fibrous texture. We notice also that the electrical resistivity of the alloy increase with an increase of the deformation level and decrease of this properties with the increasing aging time at 170 ° C.

“…DSC tests were carried out using a SETARAM (DSC131) differential scanning calorimeter. The samples for the DSC measurements weighted between 250 and 300 mg. Each sample was processed under Argon atmosphere, from 20 to 650°C, with four different heating rates (10,15,20 and 25°C/ min).…”

“…The elongated grains align parallel to the drawing direction. According to Fellah [12] and Baci et al [13], when the degree of deformation increases, the drawn wire acquires a textured microstructure so-called "wire-drawing of texture" [14,15]. Zidani et al [16] have also observed this kind of texture in the cold-drawn aluminum alloy (6101).…”

This work aims to investigate the microstructure after cold-wiredrawing process of commercial copper and its recrystallization kinetics under isochronal annealing. In this paper, the samples studied are commercial copper wires reduced at six different reductions by a wiredrawing at room temperature. Optical microscopy, Scanning Electron Microscopy (SEM), and DSC were used as characterization techniques. The samples were annealed under Argon atmosphere with four different heating rates by using DSC. The Kissinger, Ozawa, Boswell, and Starink methods were used to determine the recrystallization kinetics. The results showed that the cold-wiredrawing had caused the elongation of grains along the main axis of the wires also showed the existence of slip bands. It has been found, on the one side, that the recrystallization temperature increased and shifted to higher temperatures as the heating rate increased, which means that this reaction is thermally actived; On the other sidethe recrystallization temperature clearly shifted to lower temperatures as the deformation increased, which indicated that recrystallization is profoundly enhanced by high deforming.We noted a decrease in the activation energy values when the reduction increases, the activation energy for the most reduced materials were lower than that in the less reduced wires.

The scope of this work is to investigate the effect of the cold deformation by wire-drawing on microstructure and physical properties of industrial copper wires. Copper wires were provided by E.N.I.CA.Biskra (Algeria). We investigated some wires with different strain levels (as received, 1.20, 2.10, and ε = 3.35). X-ray diffraction, optical microscopy, and electrical resistivity measurement have been used as characterization techniques. We analyzed the photographs using "ImageJ" software and DRX patterns using PM2K software. The results revealed that the cold wire-drawing causes a lengthening of grains along the axis of wire-drawing, and introduced large amounts of defects. The results also showed, on the one hand, the decrease in crystallite size, lattice parameter, and the outer cut-off radius, on the other hand, the increase of the electrical resistivity and the dislocation density in the copper wires.
