It is a graphic method of showing the phases present in an alloy system of different temperatures and for different compositions. The solidification of the metal alloy is clearly understood by means of the phase diagram.

In phase diagrams, the phases and microstructures represented always assume equilibrium (very slow) cooling. peritectic, eutectic, cementite-intermetallic, maximum solubility of carbon in ferrite, maximum solubility of carbon in austenite points in Fe–Fe3C phase diagram A study of the constitution and structure of all steels and irons must first start with the iron-carbon equilibrium 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. Answer to IV- Consider the Fe-Fe3C phase diagram with an alloy containing 0.65%C.
In their simplest form, steels are alloys of Iron (Fe) and. Carbon (C). The Fe-C phase diagram is a fairly The figure above shows a typical Fe-Fe3C phase diagram. Case 1: For composition range between 0.022 and 0.76 (Hypo-eutectoid steel) When we come down The Fe-C phase diagram is shown below, up to around 7% Carbon. Fe3C is called cementite and lastly (for us), the "eutectic like" mixture of alpha+cementite Hence, the normal equilibrium diagram which is generally used is the metastable Fe-Fe3C diagram because it is relevant to the behaviour of most steels in 27 May 2019 The Fe - C diagram (also called the iron - carbon phase or equilibrium diagram) is a graphic representation of the respective microstructure states Maximum solubility is 2.0 % C at 1130°C. High formability, most of heat treatments begin with this single phase.
