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 ...

The data also indicated a preferential attack on ferrite, leading to an increased ... exposure to 5 % HCl significantly alters the microstructure and mechanical properties of SS 304.

Changing the carbon content of the alloy changes the microstructure of the pearlite and hence the ... between austenite and ferrite. In cooling through this zone, ferrite is precipitated on the ...
