The microstructural change related with the mechanical properties of a friction stir welded 6061 Al alloy has been investigated under various welding conditions. Frictional heat and plastic flow during friction stir welding produced fine and equiaxed grains in the stir zone, macroscopically upset and elongated grains in the thermo-mechanically affected zone caused by dynamic recovery and recrystallization. The heat-affected zone, characterized by coarse precipitates, was formed beside the weld… Expand
