Abstract
Friction-stir-welding (FSW) was performed between aluminum alloy A6061-T6 and cold-rolled steel SPCC-D. The FSWed material was aged again to recover hardness of A6061 side in the joint. Characteristics of the joints were examined on the FSWed material and its aged material in detail. The results showed that no marked defect was formed by FSW and the joints were under good condition. The microstructure near the interface of the FSWed material became very fine and no brittle compound-layer was detected around the interface. The static strength of the FSWed material was maintained at a high level. The static strength reached the same level of A6061 uniform material after aging. Further, Ti-FPB treatment slightly improved the corrosion resistance of the FSW material against salt-water.
