Q1)
Calculate the mass of different Cementites that form upon cooling from the
liquidus temperature to the room temperature of a 5wt% Fe-C alloy (White
Cast-Iron) of 100 gm.
(Solid
Solubility of C in α-Fe is 0.008 at Room Temperature)
----------------------------------------------------------
Q2) Estimate the
ratio of the width of Ferrite and Cementite in a Pearlite colony. Consider that
the density of Ferrite is 7.87 gm/cm3 and that of Cementite is 7.66
gm/cm3.

Q3) How many Iron
and Carbon atoms exist in a lattice of Fe3C, which has a complex
orthorhombic structure?
