Properties of friction-stir-welded 7075 T651 aluminum
TL;DR: Friction stir welding (FSW) was used to weld 7075 T651 aluminum, an alloy considered essentially unweldable by fusion processes as discussed by the authors, which exposed the alloy to a short time, high-temperature spike, while introducing extensive localized deformation.
