| Abstract: | The causes of worm fracture were analyzed by optical microscope, direct reading spectrometer, scanning electron microscope and election diffraction spectrometer. The results show that the sulphide inclusions in the steel are main reasons causing the worm fatigue fracture under cyclic stress. Proposals for selecting right materials are put forward. |
