Answer:
Cementite, Pearlite
A stoichiometric compound Fe3C is also known as CEMENTITE and forms when the solubility of carbon in solid iron is exceeded. The lamellar structure of α and Fe3C that develops in the iron-carbon system is called PEARLITE
Explanation:
A Cementite is a brittle compound that is made of iron and carbon. The weight of a cemientite is 6.67% of carbon and 93.3% of iron.
The stoichiometry of the Cementite is M₃C, where Fe is represented by M.
The Pearlite, known for its toughness; can be used in a several applications, such as: Cutting tools. High-strength wires.
It is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (87.5 wt%) and cementite (12.5 wt%) that occurs in some steels and cast irons.
