Abstract: The course of the liquidus curve of the component B in a simple eutectic binary system A-B, in which B exists in 2 modifications, was thermodynamically analyzed. The analysis was performed for the case that Ttr   was situated between the melting temp. of the component and the eutectic temp. in this system. Two ways were presented to find the exptl. undeterminable hypothetical melting temp., Tαf, and the enthalpy of phase transition ΔHαf at Tαf of the low-temp. modification of component B for the case that the thermodn. parameters of this component were known. Further it was found that based on the liquidus course the said unknown parameters of the component B could be detd. even for the case that ΔHβf and ΔHtr ion were not known. The study of the liquidus diagram of the binary system A-B yields previously unavailable information on the component B concerning its polymorphic transformation.
