Hydrogen effect on the electronic and structural properties of Nb-Fe alloys

Vol. 48,suppl.1

53-57

The influence of hydrogen on the electronic and structural properties of Nb1-yFey alloys has been studied with 57Fe Mössbauer spectroscopy and X-ray diffraction. No ability of hydrogen to creation of the ferromagnetic properties has been observed in this system. The results clearly indicate the ß-NbH0.85÷0.77 hydride formation in place of ?-Nb phase. The quadrupole splitting and the isomer shift of the ß-NbHx subspectrum have been considered in terms of interaction between the interstitials and the Mössbauer atoms within the hydride phase.
