What is Iron carbon diagram? Give details

Question

Accepted Answer

The iron-carbon diagram is a graphical representation of the phases and microstructures that form as carbon is added to iron.

The diagram shows the relationship between carbon content and the resulting phases in iron.
It helps in understanding the behavior of iron-carbon alloys during heating and cooling processes.
The diagram consists of three main regions: ferrite, austenite, and cementite.
The percentage of carbon determines the phase present at a given temperature.
For example, at low carbon content, ferrite is the dominant phase, while at high carbon content, cementite is formed.
The eutectoid composition (0.76% carbon) is important as it represents the lowest temperature at which austenite can transform into pearlite.
The diagram is essential for designing and controlling the heat treatment processes of steels.
