For pearlite, the two phases are present as alternating layers. A -ferrite matrix surrounds cementite particles that are extremely small and parallel and have the shape of needles.
Is pearlite a bainite ?
The primary distinction between bainite and pearlite is that the latter has a microstructure resembling plates while the former has alternating layers of cementite and ferrite.
Two distinct microstructures of steel are referred to by the names pearlite and bainite. These formations develop as a result of altering the temperature of austenite.
A form of steel microstructure known as pearlite comprises a two-layered phase made up of alternating layers of cementite and ferrite. When austenite cools down to below its eutectoid temperature (727 °C), it crystallizes. Also, cast iron and steel have similar structure. On the other hand, Bainite is a form of steel microstructure with a structure like a plate. Between pearlite and bainite, the structure is where the biggest differences lie. Additionally, when austenite cools, bainite develops until it reaches a temperature where austenite structure is no longer stable (thermodynamically unstable). Additionally, similar construction may be seen in steel as well.
