Figure 10.40 shows the continuous-cooling transformation diagram for a 0.35 wt% C iron–carbon alloy. Make a copy of this figure, and then sketch and label continuous-cooling curves to yield the following microstructures:

(a) Fine pearlite and proeutectoid ferrite

(b) Martensite

(c) Martensite and proeutectoid ferrite

(d) Coarse pearlite and proeutectoid ferrite

(e) Martensite, fine pearlite, and proeutectoid ferrite
