摘要

The isothermal section of the phase diagram of the ternary system La–Ni–Nb at 673K has been investigated by X-ray diffraction, differential thermal analysis, optical microscopy, and electron microscopy techniques. It consists of 14 single-phase regions, 25 two-phase regions, and 12 three-phases regions. At 673K, the maximum solid solubilities of Nb in Ni, LaNi₅, La₂Ni₇, LaNi₃, La₇Ni₁₆, and La₂Ni₃ is about 3, 5, 2, 3, 3, and 2at.%Nb, respectively. The composition range of the Nb in NbNi₃ is about from 23.5 to 27at.%Nb. No ternary compounds were observed.
