Isothermal section of the Er-Cu-Ga ternary system at 973 K

Résumé

Phase relations in the Er-Cu-Ga ternary system have been established at 973 K by means of powder X-ray diffraction complemented by energy dispersive spectroscopy coupled to scanning electron microscopy. The isothermal section of the phase diagram comprises eight extensions of binaries into the ternary system, ErCu1-xGax (x <= 0.5), ErCu2-xGax (x <= 1.1), ErCu5-xGax (x <= 0.5), Er5CuxGa3-x (x <= 0.60), Er3CuxGa2-x (x <= 0.24), ErCuxGa1-x (x <= 0.10), ErCuxGa2-x (x <= 0.30) and ErCuxGa3-x (x <= 0.35), as well as six ternary intermediate phases, ErCuxGa2-x (0.4 <= x <= 0.7), Er14Cu51-xGax (5.5 <= x <= 11.0), ErCu5-xGax (0.8 <= x <= 2.3), Er2Cu17-xGax (4.9 <= x <= 8.0), ErCu12-xGax (5.7 <= x <= 6.7) and Er3CuxGa11-x (1.5 <= x <= 4.4), all deriving from binary structure-types.
