Assume that the overall composition is 0.6 wt%C (and 99.4 wt%Fe) and a total weight of 10Kg. At T=727C, how many phases are present and what are their compositions and amounts?
Hint: For the very last part of this problem, first calculate the amounts "just above" and "just below" the given temperature separately, and then explain your conclusion for T=727C. You may also want to revisit lever rule and its derivation for obtaining the amount at T=727C
