Abstract
Liquid Zr46.8Ti8.2Cu7.5Ni10Be27.5 has been studied by quasielastic neutron scattering. The microscopic dynamics of this bulk glass forming alloy deviates qualitatively from simple metallic liquids; it shows two-step structural relaxation like other liquids in their supercooled state. Unexpectedly for a nonfragile system, fast β relaxation is in full accord with the mode-coupling theory of the liquid to glass transition. The long-time α relaxation suggests failure of the Stokes-Einstein relation.
