Description
The terbium-iron phase diagram has been determined using metallographic, X-ray diffraction, differential thermal analysis, and electron microprobe techniques. The terminal solubilities of the two elements are extremely restricted, of the order of 0.1 at.% for Tb in Fe. A eutectic reaction takes place at 28 at.% Fe, 8470C. The four intermetallic compounds, TbFe2, TbFe3, Tb6Fe23, and Tb2Fe17 melt non-congruently at 1187, 1212, 1276, and 13120C, respectively. The Tb2Fe17 compound appears in the rhombohedral Th2Zn17 modification on the Tb-rich side and in the hexagonal Th2Ni17 modification on the Fe-rich side of the stoichiometric composition. (Auth.)
