摘要

The Nb-rich region of refractory Nb–Ni alloy phase diagram was refined by thermal analysis, long-time annealing experiments, and electron probe microanalysis (EPMA). Both metallography and EPMA results indicate that the Nb₂Ni phase is a new stable intermetallic phase with a stoichiometric composition. Thermal analyses show that the peritectoid transition of (Nb) + Nb₇Ni₆ → Nb₂Ni occurs at the temperature of 1569.7 K. In addition, the powder XRD results suggest that the equilibrium lattice constants of Nb₇Ni₆, Nb₂Ni, and (Nb) phases are a = 4.957 Å/c = 27.000 Å, a = 11.594 Å ,and a = 3.299 Å, respectively.
