Abstract
A largest elongation of 728% was achieved in a nugget of a friction-stir-welded (FSW) Ti–6Al–4V alloy joint with a fully lamellar microstructure; this is much larger than the maximum elongation ever reported in fusion-welded nuggets (<400%). This superior superplasticity in FSW nugget vs. fusion-welded nugget was mainly attributed to easier globularization of the lamellae with smaller thickness (172 nm) and aspect ratio (8.1) in the FSW nugget during preheating and superplastic deformation.
