Abstract
This paper deals with the calculation of temperature of liquid phase in the Fe-admixture binary systems. Two cases are considered in the calculations:
1. equilibrium of pure δ-iron with ideal melt of alloying element containing iron according to the Le Chatelier-Shreder equation,
2. ideal solid solution of δ-ferrite with ideal melt of alloying element containing iron according to modified van Laar-Bowen equation by distribution coefficients.
Decrease of melting point of δ-iron in the binary systems is calculated as the difference between melting point of pure δ-iron and melting point of δ-iron containing 1 wt.% of alloying element. The melting point decrease for the polycomponent system (steel) is calculated as a sum of individual (binary) melting point decreases, which, consequently, gives the melting temperature of low-alloyed steels.

Key words
decrease of melting point, binary system Fe-X, liquidus temperature, steel, distribution coefficients, ideal systems
