Lamellar aggregate (alternate plates) of ferrite and cementite in the microstructure of iron and steel.
A distinctive two-phase lamellar structure in steel consisting of thin platelets of iron carbide (Fe3C) in a ferrite (essentially, Fe) matrix. The fine pearlitic structure (small grain size) allows maximum drawability and strengthening in steel wire, and is responsible for the mechanical properties of unhardened steel.
A microstructural constituent of steel. It is a mixture of ferrite and cementite which normally exists in lamellar form and results from the eutectoidal transformation of cooling of austenite.
A lamella aggregate of ferrite and carbide, the structure of pearlite can appear fine or coarse depending on processing.
A mixture of ferrite and cementite forming distinct layers or bands in slowly cooled carbon steels.
A constituent of steel, a decomposition product of austenite on slow cooling, containing about 0.85 percent carbon and consisting of alternate plates or laminations of alpha iron and cementite.
The lamellar aggregage of ferrite and carbide. Note: It is recommended that this word be reserved for the microstruc-tures consisting of thin plate or lamellae-that is, those that may have a pearly luster in white light. The lamellae can be very thin and resolvable only with the best microscopic equipment and technique.
The product of the eutectoid transformation of steel; a steel constituent made of lamellas of ferrite and cementite; the cementite may precipitate in other shapes (i.e., globules).
a lamellar mixture of cementite and ferrite formed during the cooling of austenite; a micro-constituent of steel and cast iron
The relatively soft phase of annealed steel made up of ferrite and cementite.
A lamellar mixture of ferrite and carbide formed by decomposing austenite of eutectoid composition.
a two-phase microstructure found in some steels and cast irons. It results from the transformation of austenite of eutectoid compositions and consists of alternating layers of alpha-ferrite and cementite.
A lamellar constituent of steel consisting of alternate layers of ferrite (alpha-iron) and cementite (iron Carbide Fe3C) and is formed on cooling austenite at 723oC. This produces a tough structure and is responsible for the mechanical properties of unhardened steel.
A metastable lamellar aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures above the bainite range.
A lamellar microstructure in carbon and alloy steels which consists of alternate layers of ferrite (alpha iron) and cementite (iron carbide) resembling mother-of-pearl.
A microconstituent of iron and steel consisting of a lamellar aggregate of ferrite and cementite (a compound of iron and carbonÃœFe3C).
is the structure of annealed or soft steel.
A microconstituent of iron and steel consisting of alternative layers of ferrite and iron carbide or cementite.
