N2 - In times of increasing energy costs automotive light weight construction is gaining more importance. The production of hybrid compounds by combining hot extrusion and compound forging is a promising method to successfully manufacture functional parts by applying resource-saving process steps. Investigations of the process chain of aluminum extrusion and subsequent die forging to produce steelreinforced aluminum parts were carried out. For the analysis extruded profiles reinforced with steel wires were used. Finite element analyses of the forging process were carried out in order to predict the position of the wires within the forged parts depending on their initial position in the extrusions. Furthermore, the grain-size distribution and the joining zone between the steel wire and the aluminum matrix before and after the forging process were investigated.
