The Effect and Influence of Vibration Aging on Residual Stresses: Residual stresses within parts are a primary cause of instability in dimensional accuracy. The stability is not only affected by the magnitude of the residual stress values, but also by the uniformity of stress distribution. JH Vibration Aging equipment has a positive effect on reducing and equalizing residual stresses, with residual stress elimination rates of approximately 30-80%.

2. The Influence of Vibration Aging on Welding Properties and Deformation Vibration treatment improves the material properties of the weld seam, particularly enhancing fracture toughness and fatigue limit, indicating that the vibration treatment technique is applicable to welding structures. The method of welding while vibrating plays a significant role in controlling welding deformation, maintaining dimensional accuracy of the workpiece, and relieving workpiece stress, as it can eliminate deformation post-welding.

3. Plastically Deformed by Vibration Aging Vibration aging causes the workpiece to undergo plastic deformation under alternating stresses, thereby relaxing the residual stresses within the workpiece. Therefore, the vibration aging process is the generation and gradual stabilization of plastic deformation in the parts, as well as the reduction and stabilization of residual stresses.

4. The Influence of Vibration Aging on Resistance to Deformation: The deformation of parts is not only dependent on the magnitude and distribution of residual stresses but also related to the relaxation rigidity and resistance to deformation. Vibration aging not only reduces and equalizes residual stresses but also enhances the material's resistance to deformation, thereby improving its elastic properties.

5. The Influence of Vibration Aging on Dimensional Accuracy Vibration aging can effectively stabilize the dimensional accuracy of components, with its effects not only evident in the smaller variation of dimensional accuracy over the long-term use, but also in achieving dimensional stability in a shorter period of time.

6. Vibration Aging and Its Effect on Hardness - Vibration aging slightly reduces the hardness of the workpiece.

7. The Impact of Vibration Aging on Fatigue Life – Vibration aging treatment primarily focuses on eliminating the effects of residual stress on fatigue life, which can significantly enhance the fatigue life of workpieces.

During the vibration process, if the applied stress and the concentrated stress from the pile-up of dislocations exceed the metal's critical shear stress, the pile-up of dislocations can be activated, leading to micro-plastic deformation within the metal and allowing for the release of residual stress.
