EBSD Analysis of SmCoFeCuZr Alloys

Abstract:

In the present study, EBSD was used for the characterization of alloys used for production of SmFeCoCuZr magnets. EBSD is adequate for texture analysis, but may give misleading results for phase identification. EBSD is not suitable for identifying phases with very similar crystalline structure, especially when the phases are crystallographically coherent, due to the superposition of Kikuchi lines. As consequence, for phase identification EBSD should be considered a complementary technique to other methods, as for example x-ray diffraction (XRD).
