The formation of ferrite and iron carbide will start at the austenite grain boundaries and the final pearlite microstructure will have lamella of ferrite and cementite ... The lower diagram ...

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 ...

another process called tempering is done by controlled reheating quenched steel to a temperature below its critical point, ...
