The temperature dependence of electrical conductivity, thermoelectric power and viscosity of Pb-based eutectic and near eutectic systems were studied. An anomalous behavior of the physical properties in the liquid binary Pb-Sn, Pb-Bi, Pb-Mg and ternary Pb-Bi-Sn melts has been revealed well above the liquidus. The temperature range of the anomalies reaches hundreds degrees and depends on the sample composition. The results obtained are interpreted in the context of the assumption that microsegregation areas formed by micro and nanoclusters exist in the eutectic and near eutectic systems.
