Austenite is a solid and, in general, will be polycrystalline. The formation of ferrite and iron carbide will start at the austenite grain boundaries and the final pearlite microstructure will have ...

When the alloy reaches the eutectoid temperature the untransformed austenite undergoes a transformation to pearlite and the already formed cementite remains unchanged. The microstructure is now a ...

In this video we'll explore metals, their microstructure, and various techniques like grain boundary strengthening, solid solution strengthening, precipitation hardening and work hardening that can be ...
