1. Compute the maximum mass fraction of proeutectoid cementite possible for a hypereutectoid iron-carbon alloy.

2. Is it possible to have an iron-carbon alloy for which the mass fractions of total cementite and proeutectoid ferrite are 0.057 and 0.36, respectively? Why or why not?

3. Is it possible to have an iron-carbon alloy for which the mass fractions of total ferrite and pearlite are 0.860 and 0.969, respectively? Why or why not?

4. Compute the mass fraction of eutectoid ce- mentite in an iron-carbon alloy that contains 1.00 wt% C.

5. The mass fraction of eutectoid cementite in an iron-carbon alloy is 0.109. On the basis of this information, is it possible to determine the composition of the alloy? If so, what is its composition? If this is not possible, explain why.
