Consult the isothermal transformation diagram in Figure 10.22. Starting with austenite at TE, determine the phase(s) that result from each of the following procedures: (a) Cool to 600 C within 1 s, hold for 100 seconds, and quench to room temperature. (b) Cool to 500 C within 1 s, hold for 100 seconds, and quench to room temperature. (c) Cool to 200 C within 1 s, hold for 100 seconds, and quench to room temperature. (d) Cool to 200 C within 1 s, heat back to 650 C for 1000 seconds, and quench to room temperature. (e) Cool at a constant rate such that 200 C is reached in 10 seconds, hold for 100 seconds, and quench to room temperature. (f) Cool at a constant rate such that 200 C is reached in 1000 seconds, hold for 100 seconds, and quench to room temperature
