• OS1505 Investigation of Fatigue Crack Behaviour on Dissimilar FSW Joints by Laminography with Synchrotron Radiation

抄録

Microstructure and a fatigue crack propagation path inside a dissimilar friction stir welded plate between A2024 and A6061 aluminum alloys were visualized with synchrotron radiation computed laminography at SPring-8. A fatigue crack propagated in a different direction from the perpendicular to fatigue loading under the influence of the plastic flow pattern in the weld. However, the fatigue crack shape projected onto the loading direction was similar to a half penny shape, and the aspect ratio decreased with increasing fatigue life. There was an interface plane between A2024 and A6061 in the welding zone but the fatigue crack propagation was not affected by the presence of the interface.
