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

Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
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.

- An intermediate shaft of a gearbox, supporting two spur gears A and B and mounted between two bearings C1 and C2, is shown in the below figure. The pitch circle diameters of gears A and B are 500 and 250 mm respectively. The shaft is made of alloy steel 20MnCr5. (\( S_{ut} = 620 \) and \( S_{yt} = 480 \) N/mm\(^2\)). The factors \( k_b \) and \( k_t \) of the ASME code are 2 and 1.5 respectively. The gears are keyed to the shaft. Determine the shaft diameter using the ASME code.
