Deformationsmechanismen

Deformationsmechanismen beschreiben mikroskopische Vorgänge, durch die Werkstoffe unter Spannung Formänderungen erfahren. In Metallen dominieren Versetzungsbewegung, mechanische Zwillingsbildung und Diffusionskriechen; in Polymeren Kettensegmentbewegung und Viskoplastizität; in Keramiken Rissausbreitung, Korngrenzengleiten und Kriechen. Die Aktivierung hängt von Temperatur, Dehnrate, Korngröße, Kristallstruktur und Defekten ab und bestimmt Festigkeit und Zähigkeit.
