Question:

Make a copy of the isothermal transformation diagram for a 1.13 wt% C iron-carbon alloy (Figure 10.39), and then on this diagram sketch and label time-temperature paths to produce the following microstructures:
(a) 6.2% proeutectoid cementite and 93.8% coarse pearlite
(b) 50% fine pearlite and 50% bainite
(c) 100% martensite
(d) 100% tempered martensite
