WebJan 1, 2004 · The knowledge of the relations between microstructure and mechanical properties, particularly the abrasion resistance and toughness, will allow designers to consider the use of partially chilled ductile iron (PCDI) for those applications in which high volume of material is worn away. The microstructure of chilled cast iron appears to be as follow; Ductile Cast Iron Nodular or spheroidal cast iron is used in many industrial applications ranging from agriculture tractors, and oil well pumps. Within Spheroidal cast iron types (SG iron), graphite appears as balls or nodules.

Abrasion and impact properties of partially chilled ductile iron
WebApr 1, 2009 · Chilled iron castings are produced by casting the molten metal against a metal chill, resulting in a surface virtually free from graphitic carbon. In the production of chilled iron, the composition is selected so that only the surfaces cast against the chill will be free from graphitic carbon. WebThis microstructure is referred to as Ledeburite or chill, it is very hard and is highly suitable for the hardness requirements of cam lobes.
