Abstract Temperature dependence of viscosity for more than ten kinds of metallic melts is analysed based on viscosity measurements. An obvious turning point is observed on the Arrhenius curves. Since viscosity is one of the physical properties sensitive to structure, its discontinuous change with temperature reveals the possible liquid--liquid structure transition in the metallic melts. Furthermore, an integrated liquid structure transition diagram of the Sn--Bi system is presented. The universality of liquid--liquid structure transition is also discussed simply.
