NEUTRON DIFFRACTION BY LIQUID SEGREGATED COPPER-LEAD ALLOYS

Neutron scattering experiments were performed on liquid Cu-Pb alloys above the miscibility gap. Two different enrichments in Cu65 were used in order to extract two of the three BHATIA-THORNTON pertial structure factors SNN and SNC. The variations of SNN and SNC with atomic concentration (xcu = 0.50, 0.64 and 0.80) and deporture from the demixtion temperature (950 < t < 1200°C) were determined and attributed to size effects
