actual parameters: temperature, T, pressure, p, and chemical composition of alloy . In presented paper the algorithm for Fe-Fe3C phase diagram calculation and
The simplest phase diagrams are pressure–temperature diagrams of a single simple substance, such as water.The axes correspond to the pressure and temperature.The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas.. The curves on the phase diagram show the points where the free energy (and …

Fe Fe3C Phase change diagram. It is an iron carbon alloy where most of the carbon is present as meta‐stable iron carbide called cementite. The upper limit of carbon content is 2%. Phase diagram helps us guess the structure of alloys and their properties. Let us look at what kinds of structure steel could have depending on its composition.
