ऑस्टेनाइट के शीतलन के दौरान गठित सीमेंटसाइट और फेराइट का एक लैमेलर मिश्रण; स्टील और कास्ट आयरन का एक घटक

pearlite's Usage Examples:

I) consists of pearlite alone.

The pearlite when highly magnified somewhat resembles the lead-tin eutectic of fig.

The difference between softness and hardness in ordinary steel is due to the permanence of a solid solution of carbon in iron if the steel has been chilled or very rapidly cooled, while if the steel is slowly cooled this solid solution breaks up into a minute complex of two substances which is called pearlite.

Iron and phosphorus unite to form a solid solution which breaks up on cooling into a pearlite.

This alloy, if allowed to solidify completely before chilling, turns into a uniform solid solution, and at still lower temperatures the solid solution breaks up into a pearlite complex.

FIC. r3.--(Stoughton.) Meshes of pearlite in a network of cementite from hyper-eutectoid steel.

- (Stoughton.) Meshes of pearlite in a netv.-ork of ferrite, from hypo-eutectoid steel.

- (Osmond.) Pearlite, steel (carbon about r%) forged and annealed at 800° C. Magnified 1000 diameters.

Forged and annealed, magnified r000 diameters, showing pearlite.

In the former case, the objects are heated only to the neighbourhood of Aci, say to 730° C., so that the 0-iron may slip into the a state, and the transformation of the austenite into pearlite and cementite may complete itself.

pearlite's Meaning':

a lamellar mixture of cementite and ferrite formed during the cooling of austenite; a constituent of steel and cast iron

Synonyms:

globular pearlite, iron carbide, lamellar mixture, ferrite, granular pearlite, cementite, cast iron, steel,

Antonyms:

uncover,
