Below one can see the peritectic part of Fe-C phase diagram. (Fig.1) Note that the CB (about 0.18wt% Carbon) represents the peritectic point. a) Find the hypo-peritectic alloy and the hyper-peritectic alloy among I, II, III, and IV. b) We will cast 0.1wt% carbon steel very much slowly. What are the phases present at 1520C? c) And, what is the weight fraction of each phases at 1520C ? (Please use a ruler to draw a tie line and to assess the lever rule.) d) Fig.2 shows schematically what happens at 1495C (peritectic temperature) for some Fe-C alloy. Estimate the composition based on the fact that the new phase has been formed largely in phase. Fig. 1 Fig
