%X A TEM study has been made to characterize the microstructure and composition of the phases in the Fe-didymium-B magnets. The main phase is the tetragonal RE2Fe14B phase. In all the samples observed, a triple junction fcc phase which frequently extended into two-grain junctions, was observed with a lattice parameter of 5.24 Å and enriched in Ce, Pr and Nd. The magnets with poorer properties had a considerable amount of the rare-earth oxide. © 1986.
