| Abstract Scope |
Recently, at the Extrusion R&D Center of Technical University Berlin (FZS) a tool to extrude a two-chamber hollow profile with single-sided variations in wall thickness was developed. The tool was tested in an extrusion campaign where billets of EN AW 6060 were pressed block on block. The desired wall thickness variations were achieved, and the profile dimensions were predominantly within the aimed tolerances. However, after extruding a certain number of billets, the tool went into a malfunction leading to several defects inside the tool. Consequently, the tool was undertaken further stress simulations to detect the cause of defects. For further characterization of the extruded profiles, specimen of all thick- and thin-walled sections were taken and tested in tensile tests. Some of these specimens were undertaken an extra heat treatment prior to the tests to achieve T4 and T6 levels in terms of ultimate tensile strength, yield strength and fracture strain. |
