The point deformation method is a sophisticated chip-less incremental metal-forming technology called flow forming that yields long tubes with precise dimensions. The aluminium alloy AA 6061 is frequently employed in the construction of ships, aeroplanes, and commercial vessels because of its exceptional mechanical qualities and strong resistance to corrosion. This work describes the creation of a fully annealed aluminium alloy 6061 tubular preform by flow forming using three rollers in one pass. This study examines the impact of three flow-forming process parameters on grain size and microstructure: feed ratio, reduction percentage, and roller axial stagger. The microstructure was observed to have lath precipitates in the transverse direction and elongated precipitates in the lengthwise direction. As the percentage of reduction went from 30 to 60, the grain sizes decreased from 138 ± 6 µm to 55 ± 20 µm. The grain size is computed using the ImageJ software. The flow-produced component microstructure is found using. The design of experiment method uses Taguchi orthogonal arrays (L9 Array).
