Abstract: Flow forming is an emerging process being widely used for manufacturing axisymmetric components that are used in the aerospace industry and automobile industries. In the present investigation, the mechanical response of the Al6101 T6 workpiece to the flow forming process has been studied. The study showed that the microhardness of the preform increased by 20.2% higher at 60% thickness reduction as compared to hardness value at 10% thickness reduction. A linear relation between the hardness variation and thickness reduction has been proposed based on experimental data. The internal diameter was found to increase with increase in the thickness reduction. In the present investigation, a 3mm increase in diameter was seen in the 120mm length.
