The Steel Section of the Iron - Carbon Diagram.
Shown
here is the steel part of the iron carbon diagram containing up to 2% Carbon.
At the eutectoid point 0.83% Carbon, Austenite which is in a solid
solution changes directly into a solid known as Pearlite which is a layered
structure consisting of layers of Ferrite and Cementite.
The steel part of the iron- carbon diagram
In order to fully
understand the changes that occur in these different alloys of steels we
will look at individual microstructures of common steel alloys.
Here
we see the various microstructures that exist in phases up to 2% Carbon
content. (The red dots represent carbon dissolved in austenite, in the
real structure these would be invisible).
Looks
pretty confusing doesn't it. Well do not worry it's really very simple,
the easiest way to work on these diagrams is to take an example. Let's
take 3 steels containing Carbon as our examples shall we?
