Kornwachstum

Wachstum in Gefügen und Kristallen

Kornwachstum

Kornwachstum bezeichnet die Vergrößerung von Kristalliten in polykristallinen Werkstoffen, getrieben durch die Reduktion der Gesamtenergie der Korngrenzen. Es tritt typischerweise bei erhöhten Temperaturen auf und kann normal, abnorm (sekundär) oder statisch/dynamisch während Umformung erfolgen. Kornwachstum beeinflusst Festigkeit, Zähigkeit, Kriech- und Diffusionseigenschaften. Seine Kinetik wird durch Temperatur, Haltezeit, Legierungselemente, Ausscheidungen und die Anwesenheit von Phasengrenzen oder Texturen kontrolliert.
