This review presents the results obtained and the deductions made from a series of microstructural studies to determine Eutectic Cell Count (ECC), Dendrite Arm Spacing (DAS), and Grain Size (GS) of hypoeutectic gray cast iron which was sand cast using metallic, non metallic, water cooled and sub- zero (Cryogenic) end chills. Analysis of the data on chilled cast iron show that the cooling rate has a marked effect on eutectic cell size, dendrite spacing and grain size. It is observed that, the number of eutectic cells as an index of graphite nucleation and the effect of these on structure and...
