Abstract
In the present work the flow of the metal in the radial extrusion of t ubular components is analysed. Different strain-hardening behaviours a re used in a commercially-available finite-element code, giving remark ably different flow behaviour of the metal. The finite-element simulat ions are verified by metal experiments. The creation of unsound compon ents is explained from the flow behaviour of the metal due to an inhom ogeneous flow followed by a difference in the strain hardening of diff erent regions of the component. Based On. the results obtained the fea tures in producing sound radial extruded components are reviewed. (C) 1998 Elsevier Science S.A.
