One of the most important problems
during solidification of ductile iron is
segregation of alloying element. Segregation of
alloying element decreases mechanical
properties of ductile iron and austempered
ductile iron. In this research, alloying element
profile as a function of intergraphite distance
was studied. Homogenization of ductile iron
using partial melting is carried out, for first
time, to homogenize the distribution of
alloying element in the matrix of ductile iron.
Results of image analyzer for homogenize and
austempered specimen showed that
homogenization using partial melting against
conventional homogenization is very effective
to uniform microstructure of ductile iron. The
results show that morphology of graphite
before and after homogenization using partial
melting has minor effect on the morphology of
graphite.
