Abstract

ABSTRACT
Austempering heat treatment process has great effects on ductile iron which turn it
to a material whose uses are increasing widely.
In the current study, austempering heat treatment process was carried out on ductile
iron using different parameters and for each case of austempering, the effect of the
austempering on both the resulted microstructures and the corrosion resistance of
the ductile iron was investigated. This was carried out to find the effect of different
austenitizing parameters on the corrosion resistance of austempered ductile iron and
to determine the optimum austempering parameters to be used to increase the
corrosion resistance of ductile iron.
