为了定量评估固有缺陷对铸造铝合金疲劳强度的影响，利用缺陷尺寸极值的统计特性，采用面积参数模型对铸造铝合金的疲劳强度进行了预测。对AC4C铝合金进行了三种缺陷尺寸的旋转弯曲疲劳试验。结果表明，疲劳强度随缺陷尺寸的增大而降低，对这些铝合金疲劳强度下限的预测与实验结果相吻合。
In order to evaluate quantitatively the effect of inherent defects on the fatigue strength of aluminum casting alloys, a fatigue strength prediction by the √(area) parameter model was performed using the statistics of extreme values of defect size. Rotating-bending fatigue tests were carried out on AC4C aluminum alloys with three levels of defect size. It was found tha the fatigue strength decreased with increasing defect size and the prediction for the lower limits of fatigue strength of these aluminum alloys was successfully correlated with the results of experiment.
