Fraunhofer IWM Develops Digital Forging Lab for Improved Microstructure Efficiency

Fraunhofer IWM has introduced a simulation model to forecast weaknesses in forged parts, driven by incomplete recrystallization. This initiative is part of a digital forging laboratory designed to achieve significant material and energy savings in forging processes amidst stringent climate regulations and the transition to green steel.

The model employs a Mean-Field approach that efficiently predicts microstructural changes during forging, enabling the simulation of large components. Validation occurred in the EU AID4GREENEST project, where it accurately identified critical zones in a turbine shaft, demonstrating the potential to mitigate process errors before production. This innovation could enhance predictive process planning, decrease energy consumption, and reduce post-processing efforts.
