| Abstract: | In this paper, the and micro analysis and metallographic examination were dealed with about the fracture failure of the hypoid gear shaft. The results exhibted that, the carburized layer in the screw with the microstructure containing acicular tempered martensite and bulk carbide was easy to form the crack source, resulting in the fracture failure of the parts. |
