Vibration Aging Technology Advantages

The vibration aging process utilizes vibration to eliminate residual stress, achieving the same effects as heat aging, and surpassing it in many performance indicators. The vibration aging process consumes less energy.Approximately 2% of the heat-treatment, with minimal equipment investment and high efficiency, it excels in energy conservation, environmental pollution reduction, and product performance enhancement, making this high-tech application shine across various industries.Wide application prospects across various industries.

Adjust, homogenize, and eliminate residual stresses

For materials that do not require a change in organizational state or are not heat-treated hardenable, vibration aging can completely replace thermal aging. Moreover, vibration aging can process large workpieces that thermal aging cannot handle.Surface vibration aging can be seen as a process of cyclic strain under periodic dynamic stress. Due to the presence of a large number of dislocations within the metallic crystal, under cyclic strain, the dislocations overcome resistance and move...Motion generates slip, leading to micro-plastic deformation of the crystal, which in turn reduces the peak residual stress. This alters the original internal stress field of the workpiece, resulting in a decrease and redistribution of internal stress, with the stress being lower and re-distributed.Under the stress level, balance is achieved. On the other hand, during vibration...Applying a certain amount of vibration energy to the workpiece in the form of mechanical energy, thereby increasing the kinetic energy of the crystals within the component and accelerating distortion.The lattice returns to its balanced position at an increased rate, leading to a more balanced lattice arrangement. This results in reduced internal damping and a decrease in the peak internal stress, with a more uniform distribution.

Enhance component deformation resistance and stabilize component processing dimensions.

Vibratory aging strengthens the crystal structure within the component's matrix, thereby enhancing the component's resistance to deformation and dimensional stability.

Enhance weldment fatigue life

Vibration aging effectively delays the initiation of cracks and reduces their propagation speed by lowering the residual stress in welds, thereby improving the fatigue life of the welded parts. The initiation of fatigue cracks always occurs first at the point of highest stress.On the weakest matrix, the test piece, after vibration aging treatment, has reduced the effects of stress concentration due to the decrease in residual stress and the homogenization of stress distribution; in addition, because of the accumulated dislocations, etc.Increased entanglement, clogging, and network density, along with higher dislocation density, make sliding along the slip zone more challenging, thereby delaying the nucleation time of fatigue cracks and extending the crack initiation life.

Enhanced Stress Corrosion Resistance in Weldments

Residual stress is a significant cause of stress corrosion. Vibration aging reduces the stress concentration effect on components, effectively eliminating and equalizing residual stresses, thereby enhancing the weldments' resistance to stress corrosion.Corrosion performance.

5. Enhance the impact energy Ak value of metal materials

Vibration aging transforms a metal specimen from a higher energy-level balance before vibration to a lower energy-level balance after vibration, placing it in a more stable state, thereby enhancing its impact work Ak value.

Vibratory aging causes two sets of specimens in impact testing to be at different energy levels prior to the impact. The specimens at a lower energy level (post-vibration specimens) will exhibit greater resistance to fracture compared to those at a higher energy level.Graded specimens (pre-vibration specimens) are stronger; that is, the impact absorbed work Ak during the impact process of the specimens after vibration aging will be greater than that of the specimens before vibration aging. Vibration aging increases the resistance to crack propagation.The number of bends during the winding process increases, leading to improved impact toughness of the material and a higher impact work Ak value.
