The temperature dependence of the chemical short-range order is
investigated by neutron scattering in stable and undercooled
metallic liquid alloys. The experiments were performed on
-- liquids forming polytetrahedral
phases and are in favour of an icosahedral topological
short-range order prevailing in the liquids. The icosahedral
short-range order is accompanied by a strong chemical order such
that the first coordination shell of a transition metal atom
consists preferentially of atoms. A decrease of
temperature leads to an enhancement of the chemical short-range
order.
