Abstract
The metallographic revelation of the microstructure of very thin wires and foils is a challenging task. How can a cross-section and a longitudinal section be prepared from a 36 μm thin wire? Or how can a flat section of a weld on 125 μm thin Nitinol sheets be successfully prepared? The preparation is to always allow for representing the crystal orientation by EBSD. Can this be achieved relying on the classical preparation of sections or do newer methods have to be used? This article presents the possibilities of a classical preparation and ion beam polishing.
Kurzfassung
Die metallgraphische Gefügedarstellung von sehr dünnen Drähten und Folien ist eine Herausforderung. Wie gelingt es von einem 36 μm dünnen Draht einen Querschliff und einen Längsschliff zu präparieren? Oder wie kann ein Flachschliff einer Schweißnaht von 125 μm dünnen Nitinolblechen gelingen? Die Präparation soll immer auch eine Darstellung der Kristallorientierung mittels EBSD ermöglichen. Kann mit klassischer Schliffpräparation dieses Ziel erreicht werden oder müssen neuere Verfahren genutzt werden? In diesem Artikel werden die Möglichkeiten von klassischer Präparation und Ionenstrahlpolieren dargestellt.
