Iron carbon equilibrium diagram

Question

Accepted Answer

The iron-carbon equilibrium diagram shows the phases and microstructures of iron-carbon alloys at different temperatures and carbon concentrations.

The diagram is also known as the iron-carbon phase diagram.
It is used to understand the behavior of iron-carbon alloys during heating and cooling processes.
The diagram shows the different phases such as ferrite, austenite, cementite, and graphite.
The carbon content affects the phase transformations and the resulting microstructures.
For example, at low carbon concentrations, ferrite is the dominant phase, while at high carbon concentrations, cementite and graphite may form.
The diagram is essential for designing and controlling heat treatments of steel to achieve desired mechanical properties.

Accepted Answer

is a graphic representation of the respective microstructure states of the alloy iron - carbon (Fe-C) depending on temperature and carbon content.

Accepted Answer

The iron-carbon diagram. It should first be pointed out that the normal equilibrium diagram really represents the metastable equilibrium between iron and iron carbide (cementite). Cementite is metastable, and the true equilibrium should be between iron and graphite.
