Electronic properties and viscosity of liquid Pb-Sn alloys

Electrical conductivity, thermopower and viscosity of liquid Pb-Sn alloys are investigated in a wide temperature range. The revealed discrepancies between heating and cooling curves of temperature dependencies of some electrophysical and structural-sensitive properties, as well as a hysteresis observed in the course of heating-cooling cycles suggest a metastable microheterogeneous structure of the Pb-Sn melts.
