5. Three steels with a composition of Fe-0.2 wt.% C, Fe-0.76 wt.% C and Fe-1.1 wt.% C are produced by melting and slowly cooling down to room temperature. By referring the phase diagram provided in figure 3, what would you expect in terms of phase changes (solidification sequence) in all three alloys as the temperature of the alloys reduces from melting temperature to room temperature? What will be the approximate weight fraction of each of those micro constituents at room...
