1. Compute the mass fractions of proeutectoid ferrite and pearlite that form in an iron- carbon alloy containing 0.35 wt% C.

2. The microstructure of an iron-carbon alloy consists of proeutectoid ferrite and pearlite; the mass fractions of these two microconstituents are 0.174 and 0.826, respectively. Determine the concentration of carbon in this alloy.

3. The mass fractions of total ferrite and total cementite in an iron-carbon alloy are 0.91 and 0.09, respectively. Is this a hypoeutectoid or hypereutectoid alloy? Why?

4. The microstructure of an iron-carbon alloy consists of proeutectoid cementite and pearlite; the mass fractions of these microconstituents are 0.11 and 0.89, respectively. Determine the following temperatures:

1250°C (2280°F), concentration of carbon in this alloy.
