摘要

In the paper, a new kind of Vibratory Stress Relief (VSR), which is called high-frequency VSR, is put forward. Firstly, the traditional VSR or low-frequency VSR is introduced, including its method and mechanism. Then a new kind of VSR experimental equipment, which exciting frequency is more than 1kHz, is suggested. The experimental results show that it could decrease the residual stress efficiently. Metallographic is also analyzed, which gives a fancy phenomenon: the number of dislocations in material decreases after high-frequency VSR, which seems that the material recovers its original and non-stress state; on the contrary, the number of dislocations in material increases after traditional VSR. Finally, the underlying prospect of new concept "high-frequency VSR" is estimated. The advanced concept will take the significant effect on the wide application of VSR and energy conservation.
