The metastable compound Nd 6 Fe 77 B 17 has been obtained by the crystallization from the amorphous phase in the Nd‐Fe‐B system. Its crystal structure is similar to that of the compound Nd 2 Fe 23 B 3 . At high temperature this metastable compound decomposes into α‐Fe and Nd 1.1 Fe 4 B 4 phases. The room temperature magnetization and coercivity are 154 A m2/kg and 12 kA/m, respectively.

    ABSTRACT: A review is given on the basic properties of 2:14:1 hard magnetic phases as well as technological procedures used for manufacturing R-Fe-B and R-Fe-C permanent magnets. First, we analyse the phase diagrams, crystal structure of hard magnetic phases and composition ranges in which these phases form solid solutions, as a result of various types of substitution. Then, the magnetic properties of and -based compounds are described. The routes used for manufacturing R-Fe-B and R-Fe-C permanent magnets are detailed. The magnets' microstructure as well as their coercivities are described in correlation with composition and manufacturing routes. The properties of nanostructure magnets are then presented. Finally, the stability of Nd-Fe-B and Nd-Fe-C magnets in various working conditions is analysed.

    ABSTRACT: Magnetic entropy changes of the NdFe12B6 compound, which was crystallized from amorphous as-quenched ribbons, were investigated. Differential thermal analysis shows that it is stable below 940 K. An abrupt change of magnetization was observed around its Curie temperature of 218 K. The maximum values of magnetic entropy change of this compound are 8.4 and 5.4 J/kg K for the applied fields of 10 and 7 kOe, respectively. These results suggest that this ternary compound can be considered as a good candidate for magnetic refrigeration.
