Abstract Discontinuous structural phase transition behaviour in seven kinds of liquid multiple component alloys are found by using a torsional oscillation viscometer. There are different phases existing in the system and the number of phases is discussed using the equilibrium thermodynamics phase rule. The phase parameters (η₀,ε) and order parameter d_f in different phase regions are calculated based on the researched results. It is found that the parameters (η₀,ε, d_f) change at the structural transition point. The diameter of the fluid clusters, d_f, is stable in each phase region, which indicates that the structure is uniform.
