Laminated metallic composites with an ultrafine-grain (UFG) structure can be successfully produced by accumulative-roll-bonding (ARB). Due to the ARB-process, the stacking sequence and the layer thickness of the laminates can be varied and thus tailored properties with a high potential for light-weight applications can be achieved. In these micro- and nanostructured laminated metallic composites, the strength of the material is further increased by super-composed effects of the additional interfaces in the laminates. It is shown on the example of titanium-aluminum-laminates that the mechanical properties don’t obey a linear rule of mixture. The high strength of titanium and the low density of aluminum were combined and extraordinary high specific strength was achieved. The strength of the laminate is close to the strength of the titanium while the overall density is lower. Microhardness testing, X-Ray diffraction and STEM near the bonding layers were used to investigate the reason for this extraordinary performance.
