The microstructure of an FeC alloy consists of proeutectoid
The microstructure of an Fe-C alloy consists of proeutectoid cementite and pearlite; the mass fraction of these two micro-constituents are 0.286 and 0.714, respectively. Determine the concentration of carbon in this alloy using the Fe-Fe3C phase diagram attached.
Solution
This problem asks that we determine the carbon concentration in an iron-carbon alloy, given themass fractions of proeutectoid ferrite and pearlite.
Wp= (Co- .022)/.74
.714*.74 = Co- .022
Co= .55wt %of C
