本研究的目的是研究一种利用高分辨率 X 射线 CT 预测球墨铸铁疲劳极限的无损方法。轴向载荷疲劳试验样品是从相当于FCD 350的大型球墨铸铁上切下的,并且使用高分辨率X射线CT对所有样品检测材料中的石墨和缺陷。使用基于四参数法的疲劳极限估计公式根据石墨和缺陷尺寸估计疲劳极限。
The purpose of this study is to investigate a nondestructive method for predicting the fatigue limit of spheroidal graphite cast iron using high resolution X-ray CT. Axial load fatigue test specimens were cut out from a large spheroidal graphite cast iron equivalent to FCD 350, and graphite and defects in the material were detected using high resolution X-ray CT for all specimens. Fatigue limit was estimated from the graphite and defect sizes using the fatigue limit estimation formula based on the four-parameter method.
