Layered pearlite
Web3. Pearlite: Pearlite is the name given to a mixture of about 87.5 percent ferrite and 12.5 percent cementite. It consists of alternate layers of ferrite and cementite in steel. Under … Webpearlite the eutectoid temperature (727C) is reached. Upon crossing this temperature to point b, the austenite transforms according to Peclite The microstructure for this eutectoid steel is lamellae of the two phases (α and Fe3C) that form simultaneously during the transformation. 9 Relative layer thickness is approximately 8 to 1
