Mechanical properties of rotary swaged steel components

Abstract The radial infeed rotary swaging is widely used as a diameter reduction forming process of axisymmetric workpieces, improving the mechanical properties with excellent near net shape forming. In present study, experiments different parameter setups were performed on steel tubes and bars under material states several resulting property modifications investigated such stress-strain curve, hardness, fatigue strength surface residual stresses. results show significant work hardening induced by an improvement in static dynamic was observed. Furthermore, hardness distribution homogenous cross section swaged workpieces. Moreover, depending conditions, stresses generated along surface.
