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 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.

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.

Pearlite is a microstructure of steel that consists of alternating layers of ferrite and cementite. It is a relatively soft and ductile material, with a moderate strength and hardness. Pearlite forms …

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 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 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 …

The colours vary as a function of the apparent spacing of the lamellae at the surface, giving rise to iridescence. 1 The name pearlite is an adaptation of the fact that natural pearls that have …
