Abstract Scope |
This study will elucidate the effects of processing parameter on material flow of AFSD (Additive Friction Stir Deposition) on repair of AA7050 via tool offset. AFSD is a novel non-fusion based additive manufacturing technique that avoids solvus temperatures during deposition of additional material. Traditional AFSD repair studies have only implemented centered depositions along the milled groove area. For the first time, tool offset will be implemented on a repair to evaluate the effect of advancing and retreating side bias, where the tool will be offset from the centerline of the groove. The mechanical properties of the different offsets were investigated with Vickers microhardness measurements, x-ray computed tomography scans and monotonic tensile testing with digital imaging correlation to visualize the localized strain around the groove area were performed. Results showed that there is an advantage with an advancing side bias compared to the retreating side bias which partially filled the groove. |
