English - English
A two-phased lamellar structure composed of alternating layers of alpha ferrite and cementite that occurs in some steels and cast irons, having a pearlescent appearance
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 glassy volcanic rock of a grayish color and pearly luster, often having a spherulitic concretionary structure due to the curved cracks produced by contraction in cooling
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
under Perlitic
A lamella aggregate of ferrite and carbide, the structure of pearlite can appear fine or coarse depending on processing
A metastable lamellar aggregate of ferrite and cementite resulting from the transformation of austenite at temperatures above the bainite range
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 mixture of cementite and ferrite formed during the cooling of austenite; a micro-constituent of steel and cast iron
