Project Status: Active
In the scope of this transfer project the Accumulative Roll Bonding (ARB) process for the manufacturing of high-strength nanocrystalline aluminum sheet metal is investigated in collaboration with the Institute for General Materials Properties. ARB processed sheet metal features an outstanding lightweight construction potential that enables significant weight reductions and fuel savings concerning body in white applications. In this context, the upscaling of the ARB process and an enhancement of the process robustness is necessary for the manufacturing of large enough strips and the commercial application in industry, respectively. Current activities are focused on the enhancement of the systems technology, especially the surface treatment, and the analysis of the resulting material properties of the sheets manufactured in the laboratory scale and in the upscaled ARB process.
