The solid-state process Additive Friction Stir (AFS) offers a unique opportunity for the manufacture and repair of Titanium products at a large-scale. AFS-processed Ti-6Al-4V yields a fully dense deposition exhibiting significant grain refinement and improved mechanical properties over parent material. Near-net shape components fabricated from solid Ti-6Al-4V feedstock material using the AFS process will be reviewed and microstructure and mechanical properties will be presented. Chemical analysis and hardness studies will evaluate scaled production ability. The interface between the titanium substrate and deposited material in repair applications will be characterized. Cost, performance, and deposition rates for the process associated with the fabrication of large components will be reviewed. Methods for establishing Process-Structure-Property relationships for the AFS process will be outlined.
