Cementite is an iron carbide compound that is a major component of the microstructure of steel. It is a hard and brittle compound that has a high carbon content. The composition of cementite is often expressed in terms of its weight percentage in relation to the overall composition of the steel.
The correct answer to the given question is option 'C': 13% Ferrite, 87% Cementite.
Explanation:
Cementite is an iron carbide compound with the chemical formula Fe3C. It is formed when carbon atoms diffuse into the iron lattice and combine with iron atoms to form a compound. The composition of cementite is 6.67% carbon and 93.33% iron by weight.
Ferrite, on the other hand, is a solid solution of carbon in iron with a very low carbon content. It is a relatively soft and ductile phase that is formed when the steel is cooled slowly. The composition of ferrite is nearly pure iron with a carbon content of less than 0.02%.
In the given question, the composition of cementite is stated as 13%. This means that the overall composition of the steel consists of 13% cementite and the remaining 87% is ferrite.
Therefore, the correct answer is option 'C': 13% Ferrite, 87% Cementite.
In summary:
- Cementite is an iron carbide compound with a composition of 6.67% carbon and 93.33% iron.
- Ferrite is a solid solution of carbon in iron with a carbon content of less than 0.02%.
- The given question states that the composition of cementite is 13%.
- Therefore, the overall composition of the steel is 13% cementite and 87% ferrite.
The correct answer to the given question is option 'C': 13% Ferrite, 87% Cementite.
