Question: Consider the TTT diagram and phase diagram for a eutectoid steel with a composition of F e = 0 . 7 6 w t %

Consider the TTT diagram and phase diagram for a eutectoid steel with a composition of Fe=0.76wt%C.
You have solution annealed (aka, annealed to equilibrium) this steel at 800C followed by rapid cooling to 500C, holding at 500C for 105 seconds followed by water quenching to room temperature. You then reheat this steel to 300C and hold it for 1 second followed by water quenching to room temperature. What constituents will the final microstructure contain?
