Kornverfeinerung

Refinement in Gefüge- und Strukturcharakterisierung

Kornverfeinerung

Kornverfeinerung beschreibt die gezielte Verringerung der Korngröße in polykristallinen Werkstoffen durch Legierungsdesign, thermomechanische Behandlung oder Zugabe von Keimbildnern. Kleinere Körner erhöhen typischerweise die Festigkeit gemäß Hall‑Petch‑Beziehung und können Zähigkeit, Ermüdungsfestigkeit und Umformbarkeit verbessern. Gleichzeitig beeinflusst Kornfeinung Diffusion, Kriechen und Korrosionsverhalten und ist ein zentrales Werkzeug des Mikrostruktur‑Engineerings.
