ANS:B - 87% ferrite & 13% cementite.

Pearlite is a microstructure found in some steels, particularly those that undergo eutectoid transformation during cooling. It consists of alternating layers of ferrite and cementite. Therefore, the correct composition of pearlite is: 87% ferrite & 13% cementite. This composition refers to the proportion of these two phases in the microstructure. Pearlitic steels are known for their combination of strength and ductility, making them widely used in various engineering applications. 1 / 2
