  The isothermal section of the phase diagram of the Gd-Fe-Ge ternary system at 773 K was investigated by X-ray powder diffraction (XRD), differential thermal analysis (DTA) and optical microscopy. The existences of 14 binary compounds, GdFe(2), GdFe(3), Gd(6)Fe(23), Gd(2)Fe(17), Fe(3)Ge, Fc(5)Ge(3), Fe(6)Ge(5), FeGe, FeGe(2), Gd(5)Ge(3),Gd(5)Ge(4), GdGe,Gd(2)Ge(3), Gd(3)Ge(5), and four ternary compounds GdFe(2)Ge(2), GdFe(6)Ge(6), Gd(2)FeGe(4), Gd(117)Fe(52)Ge(112), were confirmed. This section consists of 21 single-phase regions, 43 two-phase regions, and 23 three-phase regions. (C) 2007 Published by Elsevier B.V.

  Physico-chemical analysis techniques, including X-ray phase analysis, electron probe X-ray analysis and metallographic analysis, were employed in constructing the isothermal section of the Gd-Ti-Ge system at 1070 K. The formation of the following ternary intermetallic compounds was detected in the Gd-Ti-Ge system at 1070 K: GdTiGe (high-temperature modification of the CeFeSi structure type, space group P4/nmm, a=0.4060(1) nm, c=0.7708(1) nm; low-temperature modification of the CeScSi structure type, space group I4/mmm, a=0.4060(1) nm, c=1.5412(1) nn) and Gd2Ti3Ge4 (Sm5Ge4 structure type, space group Pnma, a=0.7044(1) nm, b=1.3494(3) nm, c=0.7187(2) nm). Differential thermal analysis was employed to investigate the melting temperature of RTiGe compounds (R=Gd-Tm). The melting temperatures of RTiGe compounds are proportional to the melting temperatures of the rare earths. (C) 1999 Elsevier Science S.A. All rights reserved.
