| Abstract Scope |
Friction stir welding (FSW) is a very advantageous joining method for many materials. The solid-state process often protects desired microstructure that provides superior material characteristics after welding. Titanium exhibits a violent phase transformation when it reaches the beta transus temperature. FSW provides a unique ability to limit the heat input in the joining process that can avoid undesirable temperatures to maintain certain microstructures. There has been a significant amount of successful work to FSW titanium with material thicknesses up to 24 mm. However, temperature differences through the material increases the difficulty to achieve a homogeneous microstructure and avoid defects in titanium FSW. These challenges are exacerbated in thick, greater than 24 mm, titanium FSW. This work will elucidate some advancements to apply FSW to thick titanium and the resulting microstructure. |
