| Abstract: | Here is stated the conclusion that vibration aging and reduce and regulate weldments residual stress and improve fatigue life on the bases of the residual stress measuring experiments, metallographic and electronic microscope observion experiments and fatigue tests.Meanwhile the internal relation between the results of vibration aging and the patten and density of dislocation in metal material is analysed in the theory of dislocation. |
