N2 - We report results from the first extended X-ray absorption fine-structure studies on icosahedral Ti53Zr27Ni20and on icosahedral Ti45Zr38Ni17which also contains 1.7 hydrogen atoms per metal atom. The experiments performed above the Ti K, Ni K. and Zr K absorption edges have allowed the determination of the local order around titanium, nickel and zirconium atoms. Significant differences are observed between these two quasicrystalline alloys in the environments of titanium and zirconium atoms, with larger Zr-Ti and Zr-Zr separations in the hydrogenated sample, suggesting that hydrogen sits preferentially near zirconium atoms.
