Mössbauer spectroscopy characterization of Zr-Nb-Fe phases

From the obtained results it can be inferred that Fe in both of the Laves phases present in this system (Zr(FeNb)2 and (ZrNb)Fe2) sees different environments, producing quadrupole splitting and hyperfine field distributions, respectively. Two types of body centered cubic β phases (Zr-rich and Nb-rich) were found having noticeable differences in their Mössbauer parameters. Furthermore it was shown that the ternary Fe(NbZr)2 compound would show magnetic character at low temperatures. Concentration dependence of the hyperfine parameters and their relations with the lattice parameters contributed to the structural characterization of the phases.
