Abstract

Abstract The isothermal section of the phase diagram of the Gd–Mn–Ni ternary system was investigated by X-ray powder diffraction, optical microanalysis and electron probe microanalysis techniques. It consists of 14 single-phase regions, 26 two-phase regions and 13 three-phase regions. At 803 K, the maximum solid solubility of Mn in Ni, Gd 2Ni 17, GdNi 5, Gd 2Ni 7, GdNi 3, GdNi 2, GdNi and Gd 3Ni is about 31, 18, 13, 10, 8, 8, 4 and 2 at%, respectively. The maximum solid solubility of Ni in Mn, GdMn 12, Gd 6Mn 23 and GdMn 2 is about 3, 4, 3 and 5 at%, respectively. The binary compounds GdNi 4 and Gd 3Ni 2 were not observed.
