Abstract

The purpose of the research was to illustrate a reconstruction of grains in case of selected cross-section of a precision cast turbine blade made of MAR M247 polycrystalline nickel-base superalloy using electron backscatter diffraction (EBSD) in the scanning electron microscope (SEM) and standard methods of quantitative metallography using imaging with light microscopy. The results of measurement of the grains performed using both methods were compared with each other with the help of a statistical test.

Kurzfassung

Der Zweck der Forschung bestand darin, eine Rekonstruktion der Körnung an einem ausgewählten Querschnitt einer Turbinenschaufel aus Feinguss, die aus einer polykristallinen Superlegierung MAR M247 auf Nickelbasis bestand, mit Hilfe der Elektronenrückstreubeugung (EBSD) im Rasterelektronenmikroskop (REM) und mittels Standardverfahren der quantitativen Metallografie mit Hilfe des Abbildens mit der Lichtmikroskopie darzustellen. Die Ergebnisse der Messung der Körnung unter Anwendung beider Verfahren wurden mit Hilfe eines statistischen Tests miteinander verglichen.
