ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.pearlite - a lamellar mixture of cementite and ferrite formed during the cooling of austenite; a constituent of steel and cast iron
cast iron - an alloy of iron containing so much carbon that it is brittle and so cannot be wrought but must be shaped by casting
steel - an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range
cementite, iron carbide - a chemical compound that is a constituent of steel and cast iron; very hard and brittle
ferrite - a solid solution in which alpha iron is the solvent
globular pearlite, granular pearlite - if steel or iron cool very slowly the cementite may occur in globules instead of in layers
lamellar mixture - a mixture in which substances occur in distinct layers
