  Fatigue crack propagation behaviors and crack length distribution on the surfaces of smooth specimens under completely reversed bending load were investigated for the as-cast and ferritized matrix spheroidal graphite cast iron. The variations of fatigue crack propagation and the crack density on the ferritized spheroidal graphite cast iron were higher than those on the as-cast spheroidal graphite cast iron. Not only the surface crack length but the maximum surface crack length in both spheroidal graphite cast irons were analyzed according to the three-parametric Weibull distribution. The variations of the maximum surface crack length distribution were greater than those of the surface crack length distribution. Moreover, it was clarified that the cycle ratio in the shape parameter α=1.0 in Weibull distribution was almost equal to the cycle ratio at which the fatigue damage process changed on the crack density curve.
