Abstract

Powder neutron diffraction of Zr(Al_xFe_1-x)₂ intermetallics (x=0-1) has been performed at room temperature in an attempt to study the variation of their bonding properties as a function of x. The Debye-Waller factors indicate a minimum of the bonding strength for both the Zr and the Fe/Al sites in the Zr(Al_xFe_1-x)₂ compounds at x=0.2. A similar minimum has also been observed by other experimental techniques, and it corresponds to the maximum hydrogen absorption in the above intermetallic system.
