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.
