“…Compacted graphite can be obtained when the residual magnesium is controlled in the range of 0.013 to 0.022% [13]. According to Fowler et.al., by using regular Fe-Mg-Si alloy during magnesium treatment process, the compacted graphite iron can be achieved if the residual magnesium in the range of 0.015-0.020% [14]. Hence, all of sample in this study could achieve the compacted graphite in cast iron.…”

Strength, toughness, machinability and damping capacity are properties of compacted graphite iron that distinguish the properties between flake graphite cast iron and spheroidal cast iron. The formation of compacted graphite can be set to achieve the required specification. The formation of compacted graphite is started from spheroidal to compacted cast iron. The residual magnesium after magnesium treatment and the solidification ratehave a significant role in the formation of compacted graphite. The high content of residual magnesium can obstruct the graphite plane to grow during the transformation from spheroidal to compacted shape. In addition, the cooling rate of the casting can be controlled by varying the casting thickness. The compacted graphite in the cast iron are characterized according to shape, size ai`nd distribution. The optimum compacted graphite in the cast iron that can be produced has 30 mm of casting thickness with 0.017 % of residual magnesium.
