Abstract Scope |
Friction stir spot welding (FSSW) of aluminum alloys and steel is conducted with an offset of a tool toward the steel side. The microstructure of FSSW joint is characterized using scanning electron microscopy and electron back scattered diffraction analysis. The mechanical property of joints is evaluated by microhardness measurements. The result of the microstructural analysis shows successful formation of FSSW joint. However, intermetallics are also observed in the stir zone, which may affect the strength of the joint. |
