Abstract
Thin wall ductile cast iron is a promising material to reduce the weight of industrial products. Because chill structures may be produced by rapid cooling in the process of making thin wall ductile cast iron, we have to examine the effect of chill structures on the fatigue properties. Fatigue tests were carried out on the ductile cast iron containing a little cementite. Fracture surface observation clarified that fracture origins were not cementite, but graphite and cast shrinkages. Fatigue lives were well arranged by the fracture origin size with the initial stress intensity facture range. When the size of cementite is the same as or smaller than that of graphite, the cementite does not effect on the fatigue properties of the ductile cast iron.
