Figures & data
Figure 1. (a) and (b) are XRD patterns and hysteresis loops of the HP and HD SmCo6.8Hf0.2 magnets at different deformation temperatures. The measurement surface of the XRD is perpendicular to the pressure direction. The test direction of the magnetic properties is parallel to the pressure direction.
Figure 2. EBSD results of the HD 850 °C magnet: (a) The inverse pole figure (IPF) quick map; (b) The misorientation angle between c-axis direction and pressing direction; (c) {0001} pole figure (PF); (d) {0001} inverse pole figure (IPF). The test surface is perpendicular to the pressure direction of the HD magnet.
Figure 3. TEM results of the HP magnet: (a) The bright field (BF) image of microstructure; (b) The selected area electron diffraction (SAED) image; (c) The inverse fast fourier transform (IFFT) image; (d-e) The Nanobeam electron diffraction(NBED) results of the designated area marked by the red dotted line [Figure (a)1, 2]. The test surface is perpendicular to the pressure direction of the HP magnet.
