determine the phase(s), the composition(s) of the phase(s), and the amounts of the
phase(s) present at 1200°C.
Solution
Phase(s): γ and L
Phase Compositions(s): Cγ= 1.9 wt% Fe CL= 3.9 wt% Fe
Amounts of Phase(s):
C 0−C ❑ 3.0−1.9
W L= = =0.55
C L −C❑ 3.9−1.9
C L−C 0 3.9−3.0
W ❑= = =0.45
C L −C❑ 3.9−1.9
