Question

A steel alloy contains 97.5 wt% Fe, 2.0 wt% Mo, and 0.5 wt% C.
(a) What is the eutectoid temperature of this alloy?
(b) What is the eutectoid composition?
(c) What is the proeutectoid phase?
Assume that there are no changes in the positions of other phase boundaries with the addition of Mo.

David · Accepted Answer

From the above figures 
Temperature for 2.0 wt% Mo is approximately 850°C 
Composition  is approximately is approximately 0.22 wt% C 
cementite is in the process of   proeutectoid
