Abstract

A study of the iron binding properties in the zr(al_xfe_1-x)₂ system, = 0,0.083,0.2, is made by utilizing the nuclear resonant photon scattering (NRPS) of 8.512 MeV γ rays from ⁵⁶Fe. Large samples of zr(al_xfe_1-x)₂ compounds, about 200 g each, were introduced into the photon beam emitted by a Cr(n,γ) source. The scattered 8.512 MeV γ radiation was detected by a large, 130 cm³ HPGe detector. An experimental set-up was designed to enable a direct comparison of the scattered intensities, thus obviating complicated self-absorption and geometrical corrections. A substitution of small amounts of Fe in ZrFe2 by Al, x = 0.083,0.2 was found to cause a reduction of the resonantly scattered intensity. This result indicates a softening of the Fe bonding strength in the corresponding compounds. Since such a substitution is also known to cause a large increase in the hydrogen absorption capacity, our results seem to conform with a prediction of the rule of reverse capacity.
