nouna lamellar mixture of cementite and ferrite formed during the cooling of austenite; a constituent of steel and cast irontype of:
Definition that contains pearlite
- martensite a solid solution of carbon in alpha-iron that is formed when steel is cooled so rapidly that the change from austenite to pearlite is suppressed; responsible for the hardness of quenched steel
- eutectoid steel a steel that contains 0.9% carbon (the eutectic point); a carbon steel with 0.9% carbon is pure pearlite
- austenite a solid solution of ferric carbide or carbon in iron; cools to form pearlite or martensite
