Study by nanoindentation of the influence of the manufacturing process on the mechanical properties of Copper-Clad Aluminum wires [PDF]
We studied the influence of the architecture of Copper-Clad Aluminum (CCA) wires produced by cold-drawing process, on the mechanical properties of materials, and the development of intermetallic compounds at the interface after annealing. Simple and architectured-CCA (A_CCA) rods, fabricated by stacking and re-drawing of original CCA wires, have been ...

Anomalous Magnetoresistance of Copper-Clad Aluminum.
Aluminum stabilizer, which is used in composite superconductors, in external fields at 4.2K prvides a remarkable enhancement of magnetoresistance as compared to predictions by conventional theory. In order to study the cause of this anomalous behavior, we measured the electric resistivities of copper-clad aluminum conductors having rectangular cross ...

Strength and HRTEM microstructure at bond interface of aluminum/copper clad materials
It is known that it is difficult to bond dissimilar metals such as aluminum and copper or aluminum and iron using diffusion bonding, because an intermetallic compound is easily produced at the bond interface and bonding strength becomes low. However it is possible to bond the dissimilar metals using the vacuum roll bonding which performs hot rolling in

Impact of hardening law on the FEM prediction of residual stresses in copper-clad aluminum wires
International audience ; Near-surface axial tensile residual stresses (from manufacturing) are reportedly detrimental to the yield strength of cold-drawn wires. Therefore, a reliable evaluation of their magnitude is necessary. The size and geometry of electrical wires can pose challenges for experimental measurement of those residual stresses. For that
