Influence of Heating Temperature on the Aluminum Used for Electric Cables

This investigation is a contribution to some scientific works that have been done on the microstructure evolution of some metals such as aluminum that are subjected to continuous heating. In this study, we present the effect of the temperature rise on the microstructural evolution of industrial aluminum wire. This material is used in the manufacture of electric cables. We used the X-ray diffraction as a characterization technique. The XRD patterns refinement was carried out using the Whole Powder Pattern Modeling WMMP) procedure Implemented in the PM2K software package. The crystallite size and the strain were estimated using the classical Williamson-Hall method (W-H plot). We observed that the increase of the temperature has caused the increase of the coherent diffraction domains (crystallites), the interplanar distance, and the lattice parameter. We noted the expansion of the elementary cell due to the temperature rise.
