Iron carbon diagram.

Question

Accepted Answer

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

The diagram shows the relationship between carbon content and the resulting microstructure of iron-carbon alloys.
It helps in understanding the properties and behavior of different types of steels and cast irons.
The diagram consists of three main regions: austenite, ferrite, and cementite.
The eutectoid point represents the composition at which austenite transforms into pearlite upon cooling.
The diagram also includes other phases such as martensite, bainite, and graphite.
The carbon content determines the hardness, strength, and other mechanical properties of the alloy.
The iron-carbon diagram is essential for heat treatment processes and alloy design in metallurgy.
