Ductile Iron - an overview | ScienceDirect Topics

Ductile iron (usually hypereutectic) is produced by ‘‘treatment’’ with magnesium immediately prior to pouring castings (see Fig. 4), followed by inoculation in much the same way as for the production of gray cast iron. Magnesium is added to the melt in the form of a master alloy (∼46% silicon, 5% magnesium, balance iron).
