摘要：
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.
