Structure of liquid Cu6Sn5 studied by neutron and x-ray diffraction

The atomic structure of liquid Cu6Sn5 alloy at 640 degrees C has been studied by means of neutron and x-ray diffraction. The experimental results were then used to perform computer modelling with the Reverse Monte-Carlo method. The simulated partial structure factors and the partial pair distribution functions agree very well with those obtained earlier by neutron diffraction with isotopic substitution. The structure of liquid Cu6Sn5 is supposed to be microheterogeneous near the melting temperature.
