A steel sample with hypoeutectoid composition (Fe + 0.5 wt% C)

A steel sample with hypoeutectoid composition (Fe + 0.5 wt% C) is rapidly cooled to 660 degree Celsius where it is maintained for 4s before being quenched to 350 degree Celsius where it is again held for 30s. Finally the sample is quenched to room temperature. Predict the sample phases at the end of the process. Hint: You need to find the right diagrams from your course notes to help you find the answers. 34% Ferrite + 33% Bainite +
