Abstract A lap joint between plates of SiC and AZX612-magnesium alloy containing aluminum was formed by friction stir spot welding using a drilling machine. The joint interface was analyzed by scanning transmission electron microscopy and energy-dispersive X-ray spectroscopy. Aluminum from the AZX612-magnesium alloy segregated along the joint interface suggesting that SiC and AZX612-magnesium alloy could be strongly joined by friction stir spot welding due to the formation of aluminum compounds. SiC and A1050-aluminum alloy plates were joined by friction stir spot welding and a tensile-shear test was performed. At 245 N, the lap joint fractured in the SiC matrix rather than the joint interface. These results confirmed that SiC and A1050-aluminum can be strongly joined due to the formation of aluminum compounds.
