The diagram shown in fig 1 actually shows two diagrams i the stable iron graphite diagram dashed lines and the metastable fe fe3c diagram.

Fe fe3c phase diagram. This video introduces major features of the fe fe3c phase diagram steel classification and basics applications for steels. This is part three in a series of screencasts about phase diagrams. Austenite containing 04 wt of carbon was cooled from 1000c to a temperature just below the eutectoid such that the equilibrium was maintained.

Binary eutectics and binary eutectoids. University of tennessee dept. What phase change is happening in the diagram.

Iron carbon phase diagram a review see callister chapter 9. The ironiron carbide fefe3c phase diagram. Transforms to fcc gaustenite at 912 c ¾γaustenitesolid solution of c in fcc fe transforms to bcc δferrite at 1395 c is not stable below the eutectic temperature 727 c.

The fe c phase diagram is a fairly complex one but we will only consider the steel part of the diagram up to around 7 carbon. The stable condition usually takes a very long time to develop specially in the low temperature and low carbon range hence the metastable diagram is of more interest. Alloying to produce a solid solution usually increases the tensile strength ts decreases the ductility.

The iron iron carbide fe fe3c phase diagram is shown in the figure below. Fe fe3c phase diagram questions 2 michaelhannan co. A study of the microstructure of all steels usually starts with the metastable fe c binary phase diagram.

Phase diagrams are useful tools to determine the number and types of phases the wt of each phase and the composition of each phase for a given t and composition of the system. Eutectoid hypo hyper alloys. Fig 1 iron carbon phase diagram.

Of materials science and engineering 2. In their simplest form steels are alloys of iron fe and carbon c. The ironiron carbide fefe3c phase diagram in their simplest form steels are alloys of iron fe and carbon c.

It provides an invaluable foundation on which to build knowledge of both carbon steels and alloy steels as well as a number of various heat treatments they are usually subjected to hardening annealing etc. The fe c phase diagram is a fairly complex one but we will only consider the steel part of the diagram up to around 7 carbon.
