Analysis of Binary Fe-X Diagrams by the Le Chatelier-Schreder Equation

The paper deals with the calculation of temperature of liquid phase in the Fe-X binary systems according to the Le Chatelier-Schroder equation. Two cases are considered in the calculations: a) equilibrium of pure delta-iron with ideal melt of alloying element containing iron, b) ideal solid solution of delta-ferrite with ideal melt of alloying element containing iron. Decrease of melting point of delta-iron in the binary systems is calculated as the diffrence between melting point of pure delta-iron and melting point of delta-iron containing 1 wt. % of alloying element. The results of the case a) are summarized in the form of periodic table. Decrease of melting point od delta-iron for the multicomponent system (steel) is calculated as the sum of melting point decrease of the individual binary systems.
