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 ...

Changing the carbon content of the alloy changes the microstructure of the pearlite and hence the mechanical properties ... Before transforming to pearlite, this material phases through the two-phase ...

The three primary phases of steel microstructure are ferrite, cementite, and austenite, and their transformations play a ...
