Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5% by mass) and cementite (12.5% by mass) that occurs in some steels and cast irons.

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.

This distinctive microstructure of steel is called pearlite. A ferrite phase has a much lower carbon content, and cementite has a much higher carbon concentration.

Pearlite is usually formed during the slow cooling of iron alloys, and can begin at a temperature of 1150°C to 723°C, depending on the composition of the alloy. It is usually a lamellar (alternate plate) …

Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons.

May 22, 2025 · Pearlite is a layered microstructure of ferrite and cementite that enhances steel strength and toughness, crucial in heat treatment and alloy design.

Pearlite is defined as a layered structure that consists of alternate layers of ferrite and cementite, which results from the transformation of austenite during slow cooling or annealing.
