| Abstract: | The equipment of strengthening shot blasting can be used to deal with the prefabricated components and X ray stress analyzer can check the surface residual stress after earburizing and quenching. It shows that the strengthening shot blast can improve greatly the residual stress of 20Cr2Ni4A. Adjusting the parameter of shol blast can get different stress values. |
