Given a plain carbon steel which has 8 % primary (or pro eutectoid) carbide, determine both overall carbon content and ferrite content.
Assume that the steel was at equilibrium just above the eutectoid temperature and then cooled immediately to 600ºC and held for 5 seconds, then quenched. What microconstituents would there be in the structure and how much of each? (Assume the cooling behavior follows the TTT curve shown)
Homework Answers
Hey dear please provide the TTT curve as mentioned in the question. Without curve the problem can't be answered. So I humbly request you to upload the question with curve so that you can be helped with the answer. Thank you.

please answer question 2,3,4
A critical feature of steel is that a considerable amount of carbon can be dissolved in the austenite, phase, (up to 2.14 w/o at 1147"C), whereas carbon is essentially insoluble in ferrite, Cooling from point d to e, just above the eutectoid but still in the an increased fraction of the +y region, will produce phase and a microstructure similar to that shown: the particles precinitates out in the form af an intermetallic.compound called iron-carbide...

HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate.
