| Abstract Scope |
This study evaluates the viability of repairing simulated damaged AA7050 plates and the effect of implementing a tool offset with Additive Friction Stir Deposition (AFSD). During deposition, the simultaneous rotational and transverse motion of the toolhead causes an asymmetrical response of the flowing deposited material. This asymmetrical effect was studied by isolating each side by performing depositions at different offsets and at different sides from the groove centerline. The research will provide insight on the relevance of such parameter when implementing repairs with AFSD and the general post repair mechanical performance. Vickers microhardness measurements were performed to observe how the heat affected zone (HAZ) is influenced by the offsets. Monotonic tests were carried out to compare the AFSD repaired specimens from the original damaged specimens. The results suggest that repairs with AFSD on AA7050 is a viable solution to salvage damaged parts. |
