Question

Answer each of the following in the context of Iron-Iron carbide equilibrium

phase diagram you have drawn:

[07]

4A

1) Gray cast iron is not an Iron-Iron carbide alloy. Evaluate.

2) What is the critical & classical difference between A3 line and Acm line?

3) From the Iron-Iron carbide equilibrium diagram, show that how will you

find out melting point of the 0.55 % carbon alloy.

4) Sketch the room temperature microstructure of 1.1 % C alloy. Label the

same, state the magnification assumed for the sketch.

5) Calculate the % of each constituent of the 1.1% C microstructure at the

room temperature.

6) State the properties of that 1.1% C alloy. Bring out properties related to

the microstructure.

7) Do you think any heat treatment is required for the microstructure

referred? Justify why that heat treatment is required.​
