Abstract
Friction stir welding is conceptually simple but metallurgically highly complex due to the combination of severe deformation and high temperature. This is particularly true in the case of precipitation strengthened alloys, such as high strength aerospace aluminium alloys, where the heat and deformation of FSW lead to profound changes in both grain structure and precipitate distribution that ultimately determine weld performance. © 2012 Trans Tech Publications, Switzerland.
