In order to establish a quantitative evaluation method for the fatigue limit of materials with defects, a 4-parameter method, based on tensile strength σB, Vicker's hardness HV, threshold stress intensity range ΔKth and maximum defect size amax, was proposed and applied to three kinds of ductile cast iron and those austempered materials. As the result, the fatigue limit values estimated by the 4-parameter method agreed well with the experimental values.
