Abstract
Microstructural characterization by combined EBSD and X-ray diffraction analysis is shown for an FCC material deformed by rolling and further heat treatment on air. The wide variety of x-rays sources combined with EBSD allows some correlations between microstructural parameters to be withdrawn by carefully analyzing x-ray peak broadening. The combination of both techniques provides a deeper understanding of anisotropic accumulation of dislocation arrays on a deformed F 138 stainless steel. The anisotropy results in a smaller peak breadth for crystal orientations with [110] planes contained on the rolling plane, further explained as resulting from a lower storage of dislocations. After heat treatment the effect is reverted and the formerly less misoriented orientations become more uniformly oriented revealing a faster dislocation migration and annihilation and/or trapping.
Kurzfassung
Behandelt wird die mikrostrukturelle Charakterisierung mittels kombinierter EBSD- und Röntgenbeugungsanalyse für einen durch Walzen und Wärmebehandlung an Luft verformten kfz-Werkstoff. Die Kombination eines breiten Spektrums an Röntgenquellen und EBSD ermöglicht auf der Grundlage einer sorgfältigen Analyse der Röntgenpeakverbreiterung die Ableitung einiger zwischen mikrostrukturellen Parametern bestehenden Korrelationen. Die Kombination beider Techniken sorgt für ein tieferes Verständnis der anisotropen Ansammlung von Versetzungsanordnungen in rostfreiem Stahl F 138. Aus der Anisotropie ergibt sich eine geringere Peakbreite für in der Walzebene enthaltene Kristallorientierungen mit [110]-Ebenen, die auch als Folge einer geringeren Einlagerung an Versetzungen erklärt werden kann. Nach der Wärmebehandlung kommt es zu einer Umkehrung des Effekts und die zuvor wenig fehlorientierten Ausrichtungen richten sich einheitlicher aus und weisen eine schnellere Versetzungswanderung und -annihilation und/oder Trapping (etwa: „Einfangen“) auf.
