T. Geisler
Abstract
The quality of technical surfaces depends significantly on the resource structures of the semi-finished product. To confirm the impact of the crystalline composition on the measuring results of scattered light technology we suggest in this article on the example of aluminium to put the measuring results in relation to the micro properties via metallographic preparation and microscopy. The main goal is to be able to determine the grain size by scattered light technology. The results determined show that a coarse grain test during an in-situ examination of aluminium is possible. The measuring method also offers the potential for the surface examination of other types of material.
Kurzfassung
Die Qualität technischer Oberflächen ergibt sich zu einem erheblichen Teil aus den Rohstoffstrukturen des Halbzeugs. Um den Einfluss der kristallinen Zusammensetzung auf die Messergebnisse der Streulichttechnik zu bestätigen, schlagen wir in diesem Beitrag am Beispiel von Aluminium vor, die Messergebnisse mit den Mikroeigenschaften mittels metallographischer Präparation und Mikroskopie in Bezug zu setzen. Das Hauptziel ist es, die Möglichkeit der Korngrößenbestimmung durch die Streulichttechnik herzuleiten. Die ermittelten Ergebnisse zeigen, dass eine Grobkornprüfung innerhalb einer Insitu-Prüfung für Aluminium möglich ist. Weiterhin hält die Messmethode auch das Potential zur Oberflächenprüfung weiterer Werkstoffarten vor.
