Mechanical Performance and Ductility of Cu/Al/Cu Clad Metals

Abstract:

The tensile mechanical performance and ductility of Cu/Al/Cu clad composite were studied. Brittle interfacial reaction compounds were observed at Cu/Al interfaces after annealing at 500°C. The ultimate tensile strength of the tri-layered Cu/Al/Cu clad plates is in close agreement with those calculated from the UTS data of separated Cu and Al layers using the rule of mixture. The loss of ductility in Cu/Al/Cu and separate Cu upon annealing at 500°C is associated with the brittle intermetallic layer. The greater ductility of as-roll-bonded Cu/Al/Cu than those of both Cu and Al is linked to the excellent interface bonding after roll-bonding. Excellent bonding at Cu/Al interface is prerequisites for improvement ductility of clad composite.
