Fatigue Behaviour of Magnesium to Steel Dissimilar Friction Stir Lap Joints
Journal Article

· Science and Technology of Welding and Joining
A short study has been conducted to assess the performance of friction stir welded Mg/steel joints under dynamic loads. The major mode of failure was found to be top Mg sheet fracture. Crack initiation is noted to have taken place at the Mg/steel interface. The fatigue life of the joints is found to be significantly different than the fatigue data of the Mg alloy obtained from the literature. The reasons behind such a difference have been examined in this work.
