“…This axisymmetric deformation not only causes the secondary phases to develop a <100> texture but also causes these filaments to have a ribbon shape, characteristic of fcc-bcc mixtures, after deformation. Zhang et al 35 reported a detailed explanation of texture formation and evolution along with the mechanical properties of Al-Mg composites during cold-drawing, which can be referred to for further details.…”

Deformation processed wires are used in the fields which demand the combination of contradictory properties such as mechanical strength and electrical conductivity. For the last 4–5 decades, scientists have focused on fabricating Cu and Al matrix wires using various plastic deformation techniques. While the high electrical conductivity is ensured through mentioned elements, the strength is achieved by orderly employment of plastic deformation and various heat treatments for basically achieving microscale filamentary structure of reinforcing elements. However, the strict selection criteria of starting materials and contradicting nature of processing regime and expected properties require proper knowledge of materials-microstructure and fabrication-property correlations. This paper summarizes the manufacturing methods, processing parameters-microstructure interactions, consequential mechanical and electrical properties and finally, current, and potential applications of deformation processed bi-metallic composite wires. It will help engineers, through provided comparative analysis, choose appropriate processing routes and starting materials for the realization of high strength/conductivity wires as well as guide what to expect in terms of targeted properties.

As common conductive materials, Al wires are used on overhead transmission lines under long-term heating conditions. In this study, the strength degradation behavior and the strength-electrical conductivity relation of the commercially pure Al wires (CPAWs) and the Al-Fe wires (AFWs) annealed at various temperatures were investigated based on the microstructure evolution. The strength degradation rate of the AFW is always higher than that of the CPAW. A linear trade-off relation between strength and electrical conductivity for the annealed Al wires are clarified. The results reveal that the mechanisms behind the trade-off relation between the strength and the electrical conductivity for the annealed CPAWs and the annealed AFWs are the recovery of dislocations and the obvious increase of grain width, which leads to the decrease of strength and the increase of electrical conductivity. The coalescence of precipitate in the AFW leads to the obvious decrease of strength, which results in the higher strength degradation rate for the AFW as compared with that for the CPAW. Consequently, the principle of microstructure design for anti-degradation of Al wire is presented.

The influence of annealing treatment on the microstructure, mechanical properties and corrosion behavior of cold-drawn Al-3.0 wt%Mg alloy was investigated by 2D-XRD, microstructure observation, tensile test, immersion test and electrochemical measurement. The relationships between microstructure and mechanical properties of the annealed alloy wire at different temperatures were studied. The result showed that during the annealing process, recrystallized grain appeared, and there was no reaction on the second phase particles. At the same time, the intensity of deformation texture decreased, while recrystallization texture appeared. With the increase in the annealing temperature, the tensile strength of the alloy decreased linearly, while the yield strength exhibited a three-stage characteristic decrease, and the elongation to failure first increased and then decreased. In addition, there was a linear relationship between the texture intensity, grain size and the strength of the alloy wire. The annealed alloy had a better corrosion resistance than the cold-drawn alloy. However, the annealed and cold-drawn alloys had similar pitting corrosion sensibility.
