Lightweighting by Tailored Forming: Bi-Material Bearing Bushing

This poster is focused on the manufacturing of bi-material bearing bushings from previously joined steel-aluminum workpieces. The forming of multi-material components is rather challenging due to the dissimilar properties of each individual material within a compound. In order to reach a nearly similar forming behavior of both materials, process-specific inductive heating strategies for bi-material workpieces are required. Due to skin-effect acting during induction heating, it is possible to create an inhomogeneous temperature distribution between steel and aluminum. In this poster, the tailored forming of a bi-material bearing bushing including the main aspects for determination of the heating strategy and the experimental temperature measurements are presented.
