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.

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 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.

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 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 …

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.

Pearlite has a diamond pyramid hardness (DPH) of approximately 200 kilograms-force per square millimetre (285,000 pounds per square inch), compared with a DPH of 70 kilograms-force per …

Oct 11, 2022 · Pearlite is a mixture composed of eutectoid ferrite and eutectoid cementite. It is one of the compositional phases of microscopic structure of steel, and the product of eutectoid …

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.

Pearlite consists of alternating layers of ferrite and cementite. These layers create a balance between toughness and hardness. Typically, pearlite makes up about 10% to 40% of the …
