Electrical conductivity, s(T), and thermoelectric power, S(T), of liquid Pb-Bi alloys of eutectic and near eutectic compositions were investigated in the “melting-solidification” temperature region. The revealed discrepancies between the heating and cooling s(T) and S(T) curves as well as a hysteresis observed in course of heating-cooling cycles suggest a metastable microheterogeneous structure of the Pb-Bi melts. A solidification mechanism is proposed.
