Can you please help me with answering the following question? I have provided a diagram to help with the question. Thank you.

Question:

Given the composition of an iron–carbon alloy containing 0.6 wt% C, at a temperature just below the eutectoid, please specify

1) whether the alloy is hypoeutectoid or hypereutectoid

2) name the proeutectoid phase

3) compute the mass fractions of proeutectoid phase and pearlite

4) make a schematic diagram of the microstructure.
