The viscosity dependence of immiscible alloys, such as Al96Bi4, Al93Bi7, Al90Bi10 and pure Bi on temperature was measured using a torsional oscillation viscometer. The variation in viscosity with temperature deviated from the Arrhenius equation near the critical temperature. The temperature dependence of the viscosity near the critical temperature could be fitted using an amended viscosity equation based on the critical dynamics theory and gas-like property of metal melts. For the amended viscosity, the activation energy is a function of temperature Ev(T) = E0 + TScf. The change in molecular degree of order is reflected by the configuration entropy, Scf. For the pure Bi melt, during the solidification process, the molecular degree of order of the melt increased and achieved long range order. For the Al-Bi immiscible alloys, the molecular degree of order increased and achieved phase separation.
