Abstract

Explosive consolidation of Sm2 Fe17 Nx and Sm2 Fe17 Nx/(Ni or Co) magnetic powders were attempted to consolidate fully dense magnetic compacts. Dense Sm2 Fe17 Nx and Sm2 Fe17 Nx/(Ni or Co) bulk materials were obtained by cylindrical explosive consolidation technique using water as a pressure transmitting medium. The values of (BH)max of Sm2 Fe17 Nx, Sm2 Fe17 Nx-5 wt%Ni and Sm2 Fe17 Nx-30 wt%Co magnets obtained were 23.8, 16.3 and 17.5 MGOe (190, 130 and 140 kJ / m3), respectively.
