Reactive elements in cast iron will be present both dissolved in the iron and coined with other elements to form particles such as oxides, sulphides, nitrides, etc. Such non-metallic particles will normally be lighter than the liquid iron, which means that there will be constant movement upwards of inclusions as the lighter particles float to the surface.

cast material [2]. This new form of cast iron immediately found uses where malleable iron, forgings, cast steel or steel fabriions would have been used. From this point, ductile cast iron grew into a world class material offering cast solu-tions at a competitive

DUCTILE IRON DATA FOR ENGINEERS 4 The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with

Cast Iron Inoculation Enhanced by Supplementary Oxy …

Inoculation is one of the most important metallurgical treatments applied to the molten cast iron immediately prior to casting, to promote solidifiion without excessive eutectic undercooling, which favors carbides formation usually with undesirable graphite morphologies. The paper focused on the separate addition of an inoculant enhancer alloy [S, O, oxy-sulfides forming elements] with a
