Abstract: | In this article, the temperature dependence of electrical resistivity (ρ-T) of Bi20Sb80 alloy was investigated by DC four-probe method. The results showed that there were two kinds of liquid–liquid structure transition (L-LST) in liquid Bi20Sb80 alloy, one was irreversible at high temperature above the liquids (815–1069°C) and the other was reversible near the melting point (600–720°C). The anomalous points on differential scanning calorimetry curve matched well with that on ρ-T curve which verified the effectiveness of the resistivity experiment. L-LST of high temperature refined the solidification organisation of Bi20Sb80 alloy to a certain extent. |
