Multiple overlapping passes of friction stir processing (FSP) were used to cover 80 mm wide region for punch stretching of 7075 Al alloy plate. The forming experiments were performed at 723 K. While a maximum depth of 52 mm (depth/punch diameter ∼ 2.7) could be achieved by punch stretching at a slow

## Abstract The trend in design and fabrication of aerospace structure is moving rapidly towards the use of composite materials and the consolidation of many pieces into large monolithic assemblies. Titanium alloy 6Al‐4V is more compatible with composite materials than aluminum alloys because of it
