A dissimilar friction stir lap weld (FSLW) of AC4C Al alloy and AZ31 Mg alloy was produced. The joining interface had a solidified microstructure with a large volume of intermetallic compounds Mg2Si, Al12Mg17 and Al3Mg2. The present study suggests that liquation phenomenon occurred during FSLW of Al and Mg alloys.
