| description | The main goal of this work was to conduct metallographic and fractographic studies, the purpose of which was to determine the cause of electric locomotive axle failure. The padding weld with a depth about 3 mm in the surface of the axle during fractographic observations was revealed. In addition, several sharp cracks inside of this weld were noticed. According to the fractographic analysis these cracks were the direct cause of the gradual spread of fatigue failure. |
