“…Similarly, a tensile strength of 1600 MPa was acquired for Cu-V composites attributed to a series of heat treatments. 33 Cu-Cr composite wires are reported to have increased tensile strength (900 MPa for 15wt%Cr) 37 compared to another study 3 where no heat treatment was employed (830 MPa for 3wt%Cr).…”

“…The dendritic structure of the ingots depends on various factors such as solidification conditions, cooling rates, relative fraction of constituents, and the ingot size. [1][2][3] Especially, high cooling rates tend to form dendrites of smaller diameter and up to second or third generation. 4,5 But a balance must be achieved as inherent stresses induced due to rapid cooling make subsequent deformation difficult.…”

“…The focus of the engineers dealing with the plastically deformed wires has sought the potential of strengthening highly conductive Cu and Al wires by combining them with lower concentrations of Cr, Ag, Nb, Fe, V, Cr, and Ta [2][3][4][5][6][7] and Ca, Mg, Nb, and Ti, respectively. [8][9][10] The minority metals act as strengthening components of the wire without significantly affecting the conductivity.…”

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.

“…The filamentary structure of double phases in the Cu-7Cr in situ composite was produced by severe cold drawing and intermediate heat treatment. The constituent concentration, cold drawing strain and heat treatment parameter strongly influence the properties [9] [10] [11]. In special, the microstructure evolution during cold drawing plays an important role in the change of the strength and conductivity with the cold drawing strain.…”

This paper studied the microstructure evolution of a deformation-processed Cu-7Cr in situ composite prepared by thermo-mechanical processing. The longitudinal and transverse sectional microstructures were analyzed using an optical microscope and a scanning electronic microscope. In the longitudinal section, the initially randomly distributed Cr dendrites in the as-cast Cu-7Cr alloy were transformed into the fibres aligned parallel to the drawing axis; the Cr dendrites experienced breaking, flattening and rotating, lapping and merging, and homogenizing and refinement during thermo-mechanical processing. In the transverse section, the initially randomly distributed Cr dendrites in the as-cast Cu-7Cr alloy were changed into the curvy ribbon like fibres; the Cr dendrites underwent breaking, flattening and rotating, folding and twisting, and irregularizing and refinement during thermo-mechanical processing.
