The isothermal section of the phase diagram of the Gd–Tb–Co ternary system at 500 °C was investigated by X-ray powder diffraction, differential thermal analysis and metallographic analysis techniques. In this isothermal section, there are nine single-phase regions, eight two-phase regions and none three-phase region. No ternary compound was found. The compounds Gd 2Co 17 and Tb 2Co 17, Gd 2Co 7 and Tb 2Co 7, GdCo 3 and TbCo 3, GdCo 2 and TbCo 2, Gd 4Co 3 and Tb 4Co 3, Gd 12Co 7 and Tb 12Co 7, Gd 3Co and Tb 3Co, Gd and Tb form a continuous series of solid solutions. In addition, we experimentally determined the vertical section of pseudobinary system and the Curie temperature of Gd 1− x Tb x Co 2 ( x from 0 to 1) series alloys.
