| Abstract: | The effect of microstructure on contact fatigue property of steel 70Cr3Mo with two kinds of heat treatment has been stu- died by means of optical metallography, SEM, TEM and XRD. The results show that the contact fatigue property of plate marten- site after quenching and tampering is higher than that of the bainite after austempering and tempering. |
