摘要
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 (ηo,ε) and order parameter dI in different phase regions are calculated based on the researched results. It is found that the parameters (ηo,ε, df) change at the structural transition point. The diameter of the fluid clusters, di, is stable in each phase region, which indicates that the structure is uniform.
