(b) Large austenite grain size with plates of ferrite nucleating intragranularly on non-metallic inclusions and growing along many different directions (courtesy of J. R. Yang). Some of the most ...

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 ...

For example, the same principles apply to the formation of cementite from austenite, but it is not difficult to distinguish ferrite from cementite morphologically. As a result of a survey of the ...

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 ...
