Question: -Fe at the eutectoid composition is cooled slowly from 800 C to just below the eutectoid temperature. Calculate the mass fractions of -ferrite and cementite

-Fe at the eutectoid composition is cooled slowly from 800 C to just below the eutectoid temperature. Calculate the mass fractions of -ferrite and cementite in the lamellar pearlite phase that forms. (b) -Fe with 1.5 wt% carbon is cooled slowly from 800 C to below the eutectoid temperature. What is the mass fraction of proeutectoid cementite that forms before pearlite starts to appear? (c) An iron-carbon alloy contains 90 wt% pearlite and 10 wt% cementite particles. What is the total carbon wt%? Is this a hypoeutectoid or hypereutectoid alloy?
