Abstract: The 773K isothermal section of the Gd-Ni-Ti system was investigated by X-ray diffractometry, optical microanalysis and electron probe microanalysis techniques. The results show that it consists of 13 single-phase regions, 23 two-phase regions and 11 three-phase regions. The maximum solid solubility of Ti in Ni, Gd₂Ni₁₇, GdNi₅ and Gd₂Ni₇ are 6.0%, 3.0%, 3.0%, and 2.5%(mole fraction), respectively.

Key words: phase diagram；isothermal section；Gd-Ni-Ti system
