Abstract

Friction stir welding (FSW) was conducted on three kinds of Al-Mg alloy of different magnesium content. Vibration fatigue life under resonant frequency was obtained according to the test standard of plane bending fatigue testing of metal plates. The crack propagation characteristic of the sample was observed with microscope and the influence of the magnesium content on resonant fatigue life of the FSW sample was also analyzed. Researches show that the resonant fatigue life of the sample with low magnesium content (about 0.44 wt%) increases after FSW, which increases from 0.9ž105 to 4.1ž105. The slip band of the FSW sample generated during FSW is beneficial to the reduction of the crack propagating driving force, thereby increasing the vibration fatigue life of the specimen. The crack propagation of high magnesium content (4.32 wt%) sample is a mixed-mode of transgranular and intergranular, which is one of the causes lead to the decrease of vibration fatigue life
