Angepasste Erstarrungsmorphologie für AlSi-Strukturbauteile (T03#)

• Subject Area: Mechanical Properties of Metallic Materials and their Microstructural Origins
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 418701707

The research project aims at realising a locally modified material design for die casting of hypoeutectic aluminium-silicon (AlSi) alloys to improve mechanical joining properties. This will be achieved and evaluated by actively and passively controlling the cooling rate during solidification throughout the manufacture of die-cast components in collaboration with Bocar GmbH and BTC GmbH. A modified microstructure prevents the formation of cracks during mechanical joining and is the basis for material designs adapted to mechanical joining processes, increasing the versatility of AlSi components.
