Methoden & Expertise zur Forschungsinfrastruktur
Derzeit können nur wenige metallische Werkstoffe so verarbeitet werden, dass anwendungsgerechte Eigenschaften resultieren. Dies liegt insbesondere am fehlenden Grundlagenverständnis für die eigenschaftsrelevanten Mechanismen. Dieses Grundlagenverständnis zu schaffen, stellt einen Schwerpunkt der Forschungsaktivitäten dar. Basierend auf diesen Erkenntnissen werden die Verfahrensschritte und die Legierungszusammensetzung so angepasst, dass Hochleistungswerkstoffe mit anwendungsgerechten Eigenschaften hergestellt werden können.
