Verformungsmechanismus

Mechanik in der Werkstofftechnik

Verformungsmechanismus

Fasst die mikroskopischen Prozesse zusammen, die während der Verformung eines Werkstoffs ablaufen. Mechanismen wie Gleiten, Versetzungsbewegung, Zwillingsbildung und Rekristallisation prägen das Gesamtverhalten unter Last und bestimmen wesentliche mechanische Eigenschaften.
