| Abstract: | The effect of vibration time-effect on the fatigue life of welded parts was investigated by the fatigue experiment and TEM analyses of the welded steel-plates before and after vibration time-effect.The investigation showed that the fatigue life of welded parts can be increased by vibration time-ef-fect. The mechanism why vibration time-effect can raise fatigue life has been come up with making use of dislocation-internal friction theory. |
