Laminated metal composites (LMCs) can be produced easily and in large quantities by the accumulative roll bonding process, where different metallic sheets are stacked and rolled together. The ARB-process allows to obtain so-called nanolaminates with layer thicknesses in the range of a few micrometers down to some tens of nanometers. With this approach many metallic materials can be combined to tailor and achieve optimum mechanical properties. The presentation
will focus on the material combinations of Al and steels, Al and Ti, and Al and Cu, which are promising candidates to achieve interesting combinations of the mechanical properties and to gain a better understanding of the deformation mechanisms. The mechanical properties have been investigated in terms of strength, fatigue properties and influences from the local strain rate sensitivity by nanoindentation measurements. The achieved properties will be compared and discussed based on the chosen alloy system and stacking sequence of the sheets.
