Regarding the product development process of sustainable goods, it is important to take the energy consumption during production, usage and for recycling into account. For the reduction of fuel consumption and CO_2 emissions during the use of passenger cars, lightweight construction is a promising approach concerning the body in white. The aim is the reduction of the wall thickness of components and ensurance of the crash performance, simultaneously. Therefore, high-strength lightweight construction materials have to be applied. In this context, the Accumulative Roll Bonding (ARB) is an innovative manufacturing process for the production of multilayered aluminum sheet metal with increased strength and nanocrystalline grain structure. Besides an enhanced strength and increased strain rate sensitivity, these sheet metals show a reduced ductility. For an economical production of components for the body in white efficient forming technologies have to be used. The essential enhancement of the formability can be realized using the Tailored Heat Treated Blanks (THTB) technology. In this context, prior the forming operation the blank is locally heat treated in specific areas and the strength is locally reduced. The formability of the blank can be increased significantly by means of a suitable heat treatment layout. This enables the application of the multilayered high strength aluminum for the body in white.
