| Sumario: | Intermetallic phases and solid solutions in the Zr-rich region of the Zr-Nb-Fe system with low Nb content are studied by Mössbauer spectroscopy complemented with X-ray diffraction, optical and scanning electron microscopy and electron microprobe analysis. The phases found in each sample were those expected from the corresponding binary Zr-Fe system. Furthermore, one of the samples showed a ternary cubic Ti2Ni type phase with a similar stoichiometry to the tetragonal Zr2Fe compound. Mössbauer parameters were suggested to this phase (IS: -0.12 mm/s, QS: 0.30 mm/s), to the bcc Zr(β) phase (IS: (-0.11 ± 0.01) mm/s, QS: (0.23±0.02) mm/s), and to the hep Zr(βT) phase (IS: (-0.24±0.02) mm/s, QS: (0.45 ± 0.02) mm/s). |
