The solidification of the metal alloy is clearly understood by means of the phase diagram.

What is the Phase Diagram? Phase Diagram is also known as equilibrium diagram or constitute diagram. 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. Importance of Phase diagram

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. Many of the basic features of this system In the latter, it is more practically useful to consider metastable equilibria involving Fe3C. In this tutorial, phase diagrams for Various phases that appear on the Iron-Carbon equilibrium phase diagram are as brittle intermetallic compound of iron & carbon, as Fe3C, contains 6.67 % C. 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 phase-pure Fe3C during growth.

In heat treatment processes of steel the very important role plays the Fe-Fe3C phase equilibrium diagram. It enables the selection of the temperature of austenitisation in respect to carbon content in steel as well as to predict the microstructure composition of annealed steel. For numerical calculation of the phase equilibrium diagrams the CALPHAD method is applied, based on the knowledge of Q.2 Using the attached Fe-Fe3C phase diagram answer the following questions: 1. Label all phases in different areas of the diagram. 2.

The Iron-Iron Carbide (Fe-Fe3C) Phase Diagram Development of Microstructure in Iron-Carbon Alloys 9.46 This problem asks that we compute the mass fractions of α ferrite and cementite in pearlite. The lever-rule expression for ferrite is Wα = CFe 3C − C0 CFe 3C − Cα and, since CFe 3C = 6.70 wt% C, C0 = 0.76 wt% C, and Cα = 0.022 wt% C
