| Abstract: | The failure analysis to the cracking in the axle sleeve of GCr15 steel after heat treatment was studied.It was showed that the microstructure of the bearing axle sleeve was normal after heat treatment,while there was a decarburized layer near the fracture.Therefore,lt could be concluded that the craking had occurred before heat treatment. |
