| Abstract Scope |
Friction extrusion describes the extrusion of metallic materials via severe plastic deformation induced by frictional heating and shear strain. A relative rotational motion between die and billet characterizes the process that offers the capability of processing a wide range of alloys at a lower energy demand due to locally introduced energy. In order to fully utilize the potential of the process to generate wires and bars with refined and homogenized microstructure, control of the shear deformation in the core area is of importance. In front of the central die bore no shearing can be imposed onto the billet material via friction and the relative velocity towards the die face reaches a minimum. Therefore, this work is investigating the mechanisms controlling the deformation and subsequent grain refinement in the core region. The experimental approach focuses on geometrical modification of billets from Al-Cu alloy to determine material conditions during friction extrusion. |
