Pearlite - Wikipedia 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 During slow cooling of an iron-carbon alloy, pearlite forms by a eutectoid reaction as austenite cools below 723 °C (1,333 °F) (the eutectoid temperature)
What is Pearlite - Definition - Material Properties In metallurgy, pearlite is a layered metallic structure of two-phases, which compose of alternating layers of ferrite (87 5 wt%) and cementite (12 5 wt%) that occurs in some steels and cast irons It is named for its resemblance to mother of pearl
Pearlite: Morphology, Crystallography and Effects | Steel . . . When austenite in iron-carbon alloys is transformed isothermally below the eutectoid temperature at small undercooling, it undergoes eutectoid transformation to produce a unique micro- structure termed “pearlite”, which was discovered by Sorby in 1864
Pearlite - an overview | ScienceDirect Topics Pearlite is essentially a composite microstructure consisting of cementite layers (which are hard and brittle) sandwiched between ferrite layers (which are soft and ductile)
What is Pearlite in Steel? - Material Welding What is Pearlite in Steel? Have you ever wondered what gives steel its remarkable strength and durability? One of the key components is a microstructure known as pearlite Pearlite is formed when austenite, the high-temperature phase of iron, undergoes a eutectoid reaction with carbon during cooling
