Entwicklung und Validierung eines numerischen Simulationsmodells zur Beschreibung der induktiven Ein- und Zweifrequenzrandschichthärtung am Beispiel von vergütetem 42CrMo4
Summary
This German engineering thesis developed a numerical model to simulate the induction hardening process for 42CrMo4 steel components. This is a manufacturing engineering study with no relevance to microplastic pollution or environmental health.
Ein Prozessmodell zur Abbildung der induktiven Ein- und Zweifrequenzhärtung unter Berücksichtigung prozessspezifischer Aspekte wurde entwickelt. Am Beispiel des Werkstoffes 42CrMo4 im vergüteten Zustand kann gezeigt werden, dass Bauteilcharakteristika wie Eigenspannungs- und Härtetiefenverläufe gut wiedergegeben werden. Basierend auf der Modellierung kann gezeigt werden, dass die Abweichung der quantitativen Wiedergabe der Eigenspannungen auf der Unterschätzung der Umwandlungsplastizität beruht.
