1) Draw iron-carbon phase diagram. According to the diagram for 99,50 wt% Fe- 0,50 wt% C alloy; (40 P) a) Schematically shetch and label the microstructures at 900C, at 750C, 700C. b) Find the fractions of total ferrite and cementite phases at 700C. c) Draw and explain the cyrstal structure of austenite and ferrite phases. d) Explain the effects of the cementite phase to the mechanical behaviour of the alloy. 1) Draw iron-carbon phase diagram.
