One of the causes of heterogeneity in glasses is phase separation in metls from which the glasses are formed. Separation of supercooled metals, i.e., of stable phases with respect to the crystalline state, is of special interest. The degree of probability of separation in supercooled melts can be estimated from the form of the liquidus lines in phase diagrams of the corresponding systems. This range of problems is directly related to the general thermodynamic theory of heterogeneous systems, developed by Gibbs, van der Waals, and others [1–4], Applications of thermodynamic theory to the problem under consideration may be found in the specialist literature [5–7], The present communication is confined to an examination of only certain special problems. First we consider the relation between the form of the liquidus line and the position of the critical point corresponding to phase separation.
