Stability in production processes - metallic semi-finished texture development
Production processes are generally dependent on a stable process window in order to be industrially usable. By modern management and control procedures, the working range can be expanded in a stable process window. Numerical methods can help to explore the limits of this window or to propose measures for its extension, the
Various scales and mechanisms of technical processes must be described reliably and predictively. The example of metallic semi-finished texture development will be described in the hot rolling as a self-organizing process, induced by the interaction between dislocations by plastic deformation on the one hand and the change of the observed microstructure, recrystallization and recovery on the other hand.
The result should serve as a prototype physically based material modeling in conjunction metallurgical process for further studies, which cover the entire process chain. Thus stable paths of optimized process management are discussed.
