Fabrication of Al/Cu Clad Sheet by Shear Extrusion
Aluminum/Copper clad sheet has been fabricated using
asymmetric extrusion method, which caused severe shear deformation
between Al and Cu plate to easily bond to each other. Interfacial
microstructure and mechanical properties of Al/Cu clad were studied
by scanning electron microscope equipped with energy dispersive
X-ray detector, micro-hardness, and tension tests. The asymmetric
extrusion bonding was very effective to provide a good interface for
atoms diffusion during subsequent annealing. The strength of bonding
was higher with the increasing extrusion ratio.
