Question: an Fe - C alloy containing 1 . 2 wt % C has a microstructure consisting of 9 5 % pearlite and 5 % proeutectoid

an Fe-C alloy containing 1.2 wt %C has a microstructure consisting of 95% pearlite and 5% proeutectoid cementite.
a) are these amounts of the consistuents to expect if the sample had been slowly cooled from the austenite region?
b) If not, draw a shematic TTT diagram for this steel and show how such a microstructure could be obtained on the diagram.
c) what is the thickness ratio of the ferrite to cementite layers of the pearlite in this sample?
