A two-phased, lamellar (or layered) structure composed of alternating layers of ferrite and cementite that occurs in some steels formed by the cooling of austenite. Pearlite is a common microstructure occurring in many grades of steels. It is hard as well as strong because of the layered structure, and is used in a variety of applications. It is wear resistant because of a strong lamellar network of ferrite and cementite.
