Question: engineering materials the microstructure of an ironcarbon alloy consists of...

Question details

Engineering Materials The microstructure of an iron-carbon alloy consists of pearlite and proeutectoid cementite; the mass fractions of these microconstituents are 0.24 and 0.76, respectively. Determine the concentration of carbon in this alloy. 1. 2. Compute the maximum mass fraction of proeutectoid cementite possible for a hypereutectoid iron-carbon alloy. 3, Compute the mass fraction of eutectoid ferrite in an iron-carbon alloy that contains 0.49 wt% C. Is it possible to have an iron-carbon alloy for which the mass fractions of total cementite and proeutectoid ferrite are 0.063 and 0.382, respectipely? Why or why not? Consider 3 kg of a 99.55 wt% Fe-0.45 wt% C alloy that is cooled to a temperature just below the eutectoid (a) How many kilograms of proeutectoid ferrite form? (b) How many kilograms of eutectoid ferrite form? (c) How many kilograms of cementite form? 4. 5.
