Accumulative roll bonding enables strenghtening of sheet materials accompanied by a reduction in ductility through the formation of an ultrafine-grained microstructure. However, the formability and in particular the failure behavior of the multilayered semi-finished products is also dependent on the bond strength between the individual layers. In the project, the cause-effect relationships between the process input parameters and the resulting interface properties are investigated. Based on a reproducible pretreatment, correlations between surface, bonding and forming properties are analyzed with the aim of improving the formability of accumulatively rolled aluminum products by suitable process measures.
