Joint performance of two types of friction welded butt joints, A2017/S45C and A6061/S45C, fabricated under several welding conditions was investigated. In the case of A2017/S45C joint, the joint strength decreased with an increase in forging pressure, and the intermetallic compounds of Al_7Cu_2Fe and iron-aluminum alloy were observed at the weld interface. On the other hand, in the case of A6061/S45C joint, the joint strength increased with an increase in forging pressure, and iron-aluminum alloy was observed at the weld interface. Such a difference in the effect of forging pressure on microstructure at the weld interface depends on the deformation property of each aluminum alloy at elevated temperature. And the thinner was the intermetallic compound or the iron-aluminum alloy, the higher was the joint strength.
