Question: Figure shows the continuous cooling transformation diagram for a 1.13 wt% C iron-carbon alloy. Make a copy of this figure and then sketch and label

Figure shows the continuous cooling transformation diagram for a 1.13 wt% C iron-carbon alloy. Make a copy of this figure and then sketch and label continuous cooling curves to yield the following microstructures:

1000 800 A 600 400 200 0.1 10 103 Time (s) 105 107 Temperature (°C)

(a) Fine pearlite and proeutectoid cementite

(b) Martensite

(d) Coarse pearlite and proeutectoid cementite

(e) Martensite, fine pearlite, and proeutectoid cementite

1000 800 A 600 400 200 0.1 10 103 Time (s) 105 107 Temperature (C)
