| Abstract: | To the fracture breakdown of aero-engine blades, the residual stress testing on it with X-ray diffraction method is carried out. Under various working status, the change laws of the residual stress on the surface of blade are analyzed. The technology using residual stress to evaluate quality of blades is discussed. A new way to control effectively the fracture breakdown of blades is acquired. |
