Friction stir welding joins superplastic Zn-22Al alloy.(Welding/Joining)

The effects of friction stir welding on the zinc-aluminum superplastic alloy Zn-22Al were discussed in terms of weldability and residual microstructures in a paper presented at the 2004 International Offshore and Polar Engineering Conference by T. Nishihara of Kokushikan University, Tokyo, Japan. Titled "Friction Stir Welding of Superplastic Zn-22Al Alloy," the paper discusses results of a study in which the alloy was friction-stir-welded on a modified milling machine, then evaluated for ductility and microstructure. Friction stir welding (FSW) is a joining method in ...
