Abstract
In order to reduce the weight of vehicles and their CO2-emissions and to increase driving range, new ways of producing hybrid material compounds must be developed to tailor the properties of the part exactly to the intended use. Lateral angular co-extrusion (LACE) offers the possibility to produce hybrid profiles. In the past, this process was used to extrude flat magnesium-titanium profiles and after further development, co-axial aluminium steel profiles.
In this study, the numerical development of a tooling system for the production of asymmetric hybrid semi-finished products extruded using LACE is presented. The co-extruded profiles, consisting of an L-profile made of steel (AISI 5120) that is filled with aluminium alloy EN AW-6082 on one side, will subsequently be formed to hybrid transverse control arms by die forging. The tool design is initially carried out for a laboratory scale extrusion in order to gain basic knowledge about the process and to quantify the influence of the different process variables like ram velocity or extrusion ratio.
