Abstract

In dual phase steels, the microstructure consists of a ferrite matrix and martensite islands along the grain boundaries of the ferrite. In this study, the microstructures of dual phase steels with different chemical compositions are characterized by applying different etchants and by using optical and electron microscopy. The most successful result was obtained with LePera and Na-metabisulfite etchants, which were applied using a special method.

Kurzfassung

In Dualphasenstählen besteht die Mikrostruktur aus einer Ferritmatrix und Martensitinseln entlang den Korngrenzen des Ferrits. In dieser Untersuchung werden die Mikrostrukturen von Dualphasenstählen mit verschiedenen chemischen Zusammensetzungen durch Aufbringen verschiedener Ätzmittel und durch Anwendung der Licht- und der Elektronenmikroskopie charakterisiert. Das erfolgreichste Ergebnis wurde mit LePera- und Na-Metabisulfit-Ätzmitteln erzielt, die unter Anwendung eines speziellen Verfahrens aufgebracht wurden.
