Martensittransformation

Martensitische Gefüge in metallischen Werkstoffen

Martensittransformation

Martensittransformation ist eine diffusionslose, scherspannungsgetriebene Phasenumwandlung, bei der durch koordinierte Atomverschiebungen eine neue Kristallstruktur entsteht. In Stählen führt die Umwandlung von Austenit zu Martensit zu stark erhöhter Härte und Festigkeit. Die Transformation verläuft athermisch, zeigt Hysterese und bildet die Grundlage für Formgedächtnislegierungen und TRIP-Stähle.
