Question

Having a eutectoid composition ——––––––––– is a microstructural product of an iron–carbon alloy consisting of alternating layers of ferrite and cementite.

• A. Austenite
• B. Delta-ferrite
• C. Martensite
• D. Pearlite

Hint:

Pearlite is a mixture of ferrite and cementite that provides a good balance of strength and ductility in steel, making it a key phase in many steel grades.

Answer 1

The Correct Option is D

Pearlite is a microstructure found in steel with a eutectoid composition (0.8% carbon), consisting of alternating layers of ferrite and cementite. This structure forms at the eutectoid temperature, and it is important for the strength and ductility of steels.
