Abstract:
The paper refers to structural and magnetic properties of the (Fe 80 Nb 6 B 14 ) 1− x Dy x ( x = 0.08, 0.10, 0.12, 0.16) bulk nanocrystalline alloys prepared by making use of the vacuum suction casting technique. The samples are in a form of rods with different diameters d = 1.5, 1, and 0.5 mm. The phase structure was investigated by XRD technique and reveals an occurrence of magnetically hard Dy 2 Fe 14 B as well as other relatively soft Dy–Fe, Fe–B, and Fe phases dependently on the Dy content. The alloys show hard magnetic properties with high coercive field up to 5.5 T (for x = 0.12 and d = 0.5 mm). The observed magnetic hardening effect with the increase of cooling rate (decrease of sample diameter d ) can be attributed to a formation of ultra‐hard magnetic objects as well as increasing role of low dimensional microstructure.
