Verfestigung

Verfestigungsmechanismen in metallischen Werkstoffen

Verfestigung

Verfestigung bezeichnet den Anstieg der Fließspannung eines Werkstoffs mit zunehmender plastischer Verformung. Mechanismen sind Versetzungswechselwirkungen, Korngrenzenverfestigung (Hall-Petch-Effekt), Mischkristall- und Ausscheidungsverfestigung. Verfestigungskennlinien werden durch Spannungs-Dehnungs-Kurven beschrieben und sind entscheidend für Umformprozesse, Duktilität und Stabilität gegen plastische Instabilitäten wie Einschnürung.
