Popis:	The present study was carried out to evaluate the microstructural and mechanical properties of a friction stir welded AZ31 with CaO Mg alloys. Friction stir welding (FSW) was performed at a tool rotation speed of 1600 rpm and a traveling speed of 80 mm/min. An intermetallic compound, Al 2 Ca, was resulted in the base metal (BM). In the stir zone (SZ), fine grains and intermetallic compound particles formed due to dynamic recrystallization and mechanical stirring. Hardness profiling showed that the SZ was harder than the BM, likely due to the presence of fine grains and thermally stable intermetallic compounds.
