Home » Electrical Engineering materials » Electrical engineering material miscellaneous » Question

The microstructure composition of pearlite for an Fe₃C diagram consists of:

1. carbon dissolved in alpha iron having a body centred cubic structure
2. carbon dissolved in gamma iron having a bodycentred cubic structure
3. a mixture of body-centred alpha having a facecentred gamma iron
4. carbon dissolved in body-centred alpha iron and an Fe₃C compound of higher carbon

Correct Option: D

The microstructure composition of pearlite for an Fe₃C diagram consists of carbon dissolved in body-centred alpha iron and an Fe₃C compound of higher carbon.
