Fig. 3: General microstructure.

Inverse pole figure maps from the electron backscatter diffraction (EBSD) analysis of the (a) Dy-free and (b) Dy-containing samples. c, d Grain size distribution, e, f backscattered electron (BSE) scanning electron microscopy (SEM) and g, h in-lens (IL) SEM images of the Dy-free and Dy-containing magnets, respectively. The selected area electron diffraction (SAED) patterns obtained from the respective phases are also shown in Fig. 3.
