Scanning electron microscopic images of fractured cast iron samples under cyclic loading

Scanning electron microscopic images of fractured ductile cast iron samples are enclosed. Rotary fully-reversed bending Fatigue tests were done on standard GJS-700 specimens, extracted from the crankshaft of an engine, under cyclic loading. Then, the fracture surface of samples was examined by scanning electron microscopy to find striation marks due to the fatigue phenomenon.

本数据集包含断裂球墨铸铁（ductile cast iron）试样的扫描电子显微图像。研究人员对取自某发动机曲轴的标准GJS-700试样开展了循环载荷下的旋转全反向弯曲疲劳试验。随后，通过扫描电子显微镜（Scanning Electron Microscopy, SEM）对试样的断口形貌进行观测，以甄别由疲劳效应引发的疲劳辉纹（striation marks）。
