| Abstract Scope |
In this work additive manufacturing using friction stir deposition from wrought AA2011 bar of 20 mm diameter against aluminum substrate was carried out. The effect of the spindle rotation rate (600-1200 rpm) and the feeding speed (3-9mm/min) on the deposition process, the microstructure and the hardness of the deposited parts were investigated. During the process after fixing the bar on the spindle shank and while rotating, the bar approaches the substrate at a constant feeding speed, the bar plastically deformed due to the friction between the rotating bar and the fixed substrate that causes the material to transfer from the bar to the substrate under the continuous feeding. The shape of the deposited parts varied by increasing the feeding speed with two diameters, small diameter of 20mm towards the substrate and large diameter of 40 mm at the top. The ratio between the two diameters varied with the feeding speed. |
