Kinetics of Liquid Structure Transition of Sn--(40wt%)Bi Melt

The kinetics of temperature-induced liquid--liquid structure transition (TI-LLST) process in Sn--(40wt%)Bi melt is investigated in isothermal and continuous
heating experiments with electrical resistivity method. The time evolution pattern of the electrical resistivity suggested the transition mechanism of TI-LLST for Sn--(40wt%)Bi melt in accordance with the autocatalytic reaction model, which is an indication of nucleation-growth type. With the calculated reaction rate constant K_T and apparent activation energy ΔE, we deduce the
reason for the characteristics of TI-LLST. The present result may be beneficial for further understanding of the nature of TI-LLST.
