Plastische Verformung

Plastische Verformung ist die bleibende Formänderung eines Werkstoffs über die elastische Grenze hinaus. In kristallinen Metallen erfolgt sie primär durch Versetzungsbewegung und -vermehrung, unterstützt durch Zwillingsbildung oder Gleitbandlokalisierung. In amorphen Werkstoffen wirken Schersbänder. Spannungszustand, Temperatur, Dehnrate, Korngröße und Ausscheidungen steuern Fließspannung, Verfestigung, Duktilität und Versagensmechanismen.
