could you please do e?

thank you

2. Using the isothermal transformation diagram for an iron-carbon alloy of eutectoid composition (Figure below), specify the nature of the final microstructure (in terms of microconstituents present and approximate percentages of each) of a small specimen that has been subjected to the following time-temperature treatments. In each case assume that the specimen begins at 760C(1400F) and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure. a. Cool rapidly to 700C(1290F), hold for 104s, then quench to room temperature. b. Reheat the specimen in part (a) to 700C(1290F) for 20h. c. Rapidly cool to 600C(1110F), hold for 4s, rapidly cool to 450C(840F), hold for 10s, then quench to room temperature. d. Cool rapidly to 400C(750F), hold for 2s, then quench to room temperature. e. Cool rapidly to 400C(750F), hold for 20s, then quench to room temperature. he complete isothermal ransformation diagram for an iron-carbon lloy of eutectoid composition: A, austenite: 1, bainite; M, martensite; P, pearlite
