Versetzungsmechanismen

Versetzungen in Werkstoffen

Versetzungsmechanismen

Die Untersuchung von Versetzungsmechanismen liefert entscheidende Einblicke in die Prozesse der plastischen Verformung in kristallinen Werkstoffen. Wechselwirkungen zwischen Versetzungen und anderen Defekten bestimmen maßgeblich die mechanischen Eigenschaften und die Duktilität, was für die Entwicklung leistungsfähiger Materialien von großer Bedeutung ist.
