Abstract Scope |
Nanostructured layered metallic composites of the e.g. Cu/Fe, Cu/Nb and many other systems have been produced successfully by accumulative roll bonding (ARB). In the Cu/Nb system a layer thickness down to only one nanometer has been achieved by a combined process of ARB and subsequent conventional rolling steps. Such ultrathin composites have demonstrated very interesting properties in terms of strength, ductility and conductivity. The strength of the ultrathin nanocomposites increases to very high numbers accompanied with more or less no loss in ductility. The conductivity on the other hand strongly decreases below a layer thickness of 100 nm. Furthermore the thermal stability of the nanostructured composites is exceptionally high due to the immiscibility of the individual layers.
Finding the optimum layer thickness with respect to the mechanical and functional properties will be discussed in detail. |
