Interfacial strength development of roll-bonded aluminium/copper metal laminates

The development of the phases in the interface of roll-bonded Al/Cu metal laminates controls the strength. Phase development as a function of sintering time was monitored via X-ray diffraction and X-ray mapping. Both techniques revealed essentially the same phase presence and highlighted a limitation of X-ray diffraction. Initial rolling reduction has no effect on phase development but does affect the interface thickness.
