Abstract
Over the last years, multi-material design aiming on manufacturing of application-optimized technical components has been gaining in importance. In this context, combination of steel and aluminum offers an effective solution for implementation of lightweight concepts due to its high strength-to-weight ratio. The steel can be placed in high- stressed . areas, where high performance properties are required, while the aluminum can be used for the rest of the. part, in order to save the component total weight. Due to dissimilar material properties of steel and aluminum, the process design for bi-metal forming is very challenging and requires a process-specific heating strategy, which development is in focus of this paper. The current study involves the potential for creating bi-metal bearing bushings consisting of steel 20MnCr5 and aluminum AA-6082 by closed-die-forging. Firstly, an overview of modem technologies for bi-metal forming is given. In following, the scientific issues and demanding challenges within this study- Are described for both, heating and subsequent forming. Results of the initial computer modeling and experimental validation of the heating behavior arc presented. Subsequently, the experimental forging tests were conducted with achieved temperature gradients. The forged parts were metallographically investigated to examine the resulting quality of the joining zone. Based on the obtained findings, the optimization proposals for the entire process are discussed.
