Abstract

In fractography, different fracture surfaces are examined and described with regard to their appearance and morphology. In this context, the fracture surface carries information on the fracture event and on the material, as the morphology reflects the microstructure as well as the physical properties. In the course of this work it is show that the fractographic examination may go beyond just viewing the fracture surfaces. In addition to that, some fracture appearances are presented that are rarely encountered in practice.

Kurzfassung

In der Fraktographie werden verschiedenste Bruchflächen untersucht und bezüglich ihrer Erscheinungsform und Morphologie beschrieben. Dabei ist die Bruchfläche ein Datenträger des Bruchereignisses und auch für den Werkstoff, da sich sowohl die Mikrostruktur als auch die physikalischen Eigenschaften in der Bruchmorphologie widerspiegeln. Im Rahmen dieses Beitrages wird dargelegt, dass die fraktographische Untersuchung über das bloße Betrachten der Bruchflächen hinausgehen kann. Außerdem werden einige Brucherscheinungsformen gezeigt, denen man in der Praxis eher selten begegnet.
