08/11/2023 – Predicting microstructure evolution during wire manufacturing
Simulation-based microstructure prediction
The simulation of material behaviour is an important tool in process design. A model developed at Fraunhofer IWM allows predicting microstructure evolution during wire manufacturing. A simulation program makes the model available for practical application.
