Influence of Different Etchants on the Representation of Microstructures in Nickel Alloys

Abstract
This work presents a comparison of selected nickel alloys of the same condition which were treated by means of specifically chosen etching techniques. Microstructures on microscope images of wrought Alloy 617, a casting variant of Alloy 625, a polycrystalline casting alloy IN-738 LC, as well as of a monocrystalline superalloy CM 247 LC SX, respectively, are juxtaposed and evaluated. This approach allows for a comprehensive optical microscopy characterization of the characteristic microstructural features.
Kurzfassung
In dieser Arbeit werden jeweils gleiche Zustände ausgewählter Nickellegierungen, die mit gezielt gewählten Ätzverfahren behandelt wurden, vergleichend dargestellt. In lichtoptischen Aufnahmen wird die Mikrostruktur der Knetlegierung Alloy 617, einer Gussvariante von Alloy 625, einer polykristallinen Gusslegierung IN-738 LC sowie einer einkristallinen Superlegierung CM 247 LC SX gegenübergestellt und bewertet. Somit wird eine vollständige lichtoptische Charakterisierung der kennzeichnenden Gefügemerkmale möglich.
