please answer this question in very good handwriting or type it computer and full detail
3. Using the isothermal transformation diagram for a 1.13 wt% C steel alloy (Figure 11.49 in your book), determine the final microstructure (in terms of just the microconstituents present) of a small specimen that has been subjected to the following time-temperature treatments. In each case assume that the specimen begins at 920°C 01690°F) and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure. (a) Rapidly cool to 775 C (1430 F), hold for 500 s, then quench to room temperature. (b) Rapidly cool to 700eC(1290°F), hold at this temperature for 105 s, then quench to room temperature. (c) Rapidly cool to 350°C (660 F), hold for 300 s, then quench to room temperature. (d) Rapidly cool to 600°C (1110 F), hold at this temperature for 7 s, rapidly cool to 450°C (840 F, hold at this temperature for 4 s, then quench to room temperature.
