Abstract:  Thermodynamics of phase equilibria in the binary condensed systems which form with respect to "solidus—liquidus" equilibrium continuous solid solutions and which have in the subsolidus region polymorphic modifications of components is discussed. The polymorphic modifications can form either no solid solutions, either limiting or continuous solid solutions. Rules describing the course of curves of monovariant phase equilibrium in the vicinity of eutectoid points were derived assuming classical ideal behaviour of all solid solutions taking part in the equilibrium. Also the rules which should be obeyed by the slopes of tangents to the curves of monovariant phase equilibrium of continuous solid solutions in subsolidus region are presented.
