Abstract

The effect of plastic deformation by wire drawing on structure and properties of an industrial electric aluminum wire has been studied. Some heat treatments were applied on the drawn wires. For this investigation, different techniques were used: optical microscopy, transmission electron microscopy, hardness measurements and differential scanning calorimetry. We have observed texture structure along axis wire after the wire drawing process. This cold plastic deformation causes a phenomenon of material consolidation. However, the heat treatments applied on drawn wires lead to recrystallization phenomenon. We have found that in low temperature, the recrystallization reaction is observed only for reduction by wire drawing greater than 30 %.
