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 ...

In cooling through this zone, ferrite is precipitated on the austenite grain boundaries. As the temperature is reduced, the austenite composition moves towards the eutectoid value, and at 727 C has ...

WHEN bicrystals are subjected to a constant shear stress parallel to the boundary plane, the grain boundary sliding velocity decreases with time 1–4. We wish to report some experiments which ...

In this video we'll explore metals, their microstructure, and various techniques like grain boundary strengthening ... that shows us the different phases like ferrite, austenite and cementite ...
