Effect of Magnesium as Spherodizer on Graphite Morphology in Ductile Cast Iron
Keywords:
Cast Iron; Magnesium, Nodularity, Microstructure, Mechanical PropertiesAbstract
Cast Iron is an alloy of Fe-C-Si with carbon content greater than 2.11% and is used in the as-cast state or after
treatment. Magnesium was added in varying quantities to cast iron and by studying the graphite morphology, nodularity
and mechanical properties it was found that addition of 0.035% Mg to cast iron makes the mechanical properties of this
cast iron comparable to graded heat treated material 65-45-12. Moreover due to increased nodulairty there could also be
increase in machinability which needs to be investigated further
