Pearlite comprises of__________________?
Correct answer: D. 87% ferrite & 13% cementite
- A. 87% cementite & 13% Fe
- B. 87% ferrite & 13% C
- C. 93.33% ferrite & 6.67% C
- D. 87% ferrite & 13% cementite
Explanation
Pearlite is the lamellar mixture of ferrite and cementite formed from austenite, containing approximately 87% ferrite and 13% cementite by mass. Its carbon content is about 0.8%, so the option stating 6.67% carbon confuses cementite composition with pearlite composition.
