Resumen:
Samples with the following compositions: Zr62Nb14Fe24, Zr65Nb10Fe25 and Zr52Nb10Fe38 were studied by Mössbauer spectroscopy. All of them showed a ternary cubic Ti2Ni-type phase (QS: 0.30 ± 0.02, IS: -0.14 ± 0.01) and traces of Zr2Fe phase (QS: 0.86 ± 0.03, IS: -0.29 ± 0.01). Zrβ phase (QS: 0.22 ± 0.01, IS: -0.11 ± 0.01) was also detected except in the case of the richer Fe sample. In addition to these expected phases, a hexagonal MgZn2-type phase was determined. The assigned parameters for this phase are: QS: 0.38 ± 0.04, IS: -0.28 ± 0.02. These results suggest a revision of the diagram.
