We present here the influence of reduction ratio during roll bonding on the microstructural evolution, mechanical properties and room-temperature formability of Al-Cu 2-ply clad metal. The effect of reduction ratio upon the evolution of interface microstructure is first analyzed by means of scanning electron microscope (SEM) and transmission electron microscope (TEM) attached with energy dispersive spectroscopy (EDS). Taking the difference of microstructure upon reduction ratio into account, mechanical properties of this composite were evaluated by uniaxial tensile and peel tests. Formability was also verified by applying Erichsen tests.
