Answer to Question #258490 in Mechanical Engineering for A jaif

Question #258490

Draw neat iron – iron carbide equilibrium diagram and indicate phases clearly.


a) Explain various invariant reactions with help of microstructures.


b) Consider a hypo eutectoid steel (C0 = 0.012 + 0.78 [X/106]) and hyper eutectoid steel ((C0 = 0.78 + 0.012 [X/106]) compositions and estimate pro-eutectoid phase fractions, for the given compositions.


c)Also estimate compositions of ferrite, Fe3C and phase fractions just below eutectoid temperature.


Note: Also calculate your compositions from the given equation (X is your sl. number) and indicate it. For each subsections (a,b,c) please draw a separate Fe-Fe3C diagram.
