A). Draw only the eutectoid portion of the Fe-C phase

a). Draw only the eutectoid portion of the Fe-C phase diagram. Indicate all the important compositions and temperatures.

b). Also label all the areas with (i) phases and (ii) micro constituents on two separate Fe-C phase diagrams containing only eutectoid portions.

c). Write down the names of the equilibrium micro constituents at room temperatures for 1040, 1077 and 10120 steels. Draw their microstructures.
