a mixture in which substances occur in distinct layers

an alloy of iron containing so much carbon that it is brittle and so cannot be wrought but must be shaped by casting

an alloy of iron with small amounts of carbon; widely used in construction; mechanical properties can be varied over a wide range

a chemical compound that is a constituent of steel and cast iron; very hard and brittle

a solid solution in which alpha iron is the solvent

if steel or iron cool very slowly the cementite may occur in globules instead of in layers
