Make a copy of the isothermal transformation diagram for an iron-carbon alloy of eutectoid composition (Figure 10.22) and then sketch and label time-temperature paths on this diagram to produce the following microstructures:
(a) 100% coarse pearlite
(b) 50% martensite and 50% austenite
(c) 50% coarse pearlite, 25% bainite, and 25% martensite
