The influence of oxide layers on the physical properties of the bonding of composites will be investigated using molecular dynamics simulations to understand the process of roll bonding. The objective is to identify process conditions that lead to particularly high-quality, metallurgically-bonded compounds. The basic dependencies of the bond strength on oxygen concentration, temperature and oxide layer thickness will be investigated for interfaces. The hardness of the materials as an indicator for the quality of the joint will be determined experimentally by nanoindentation and compared with simulation values.
