Question:

Make a copy of the isothermal transformation diagram for a 0.45 wt% C iron-carbon alloy (Figure 10.39), and then sketch and label on this diagram the time-temperature paths to produce the following microstructures:
(a) 42% proeutectoid ferrite and 58% coarse pearlite
(b) 50% fine pearlite and 50% bainite
(c) 100% martensite
(d) 50% martensite and 50% austenite
