- Abstract
As a result of the general need for lightweight product design, multi-material systems are gaining in importance. In addition to reducing component weight, the combination of different materials in a single component allows other properties to be locally tailored to its application. This topic is the aim of research within the Collaborative Research Centre (CRC) 1153 “Tailored Forming”, which investigates the entire process chain for the production of hybrid components from previously joined workpieces. One of the main focal points is the investigation of the joining zone development of steel-aluminium products (20MnCr5 - EN AW-6082) during friction welding and further processing in different forming processes. The overall strength of the multi-material component is determined by joint strength. In order to improve the properties of the joining zone by thermomechanical treatment, a backward can (BC) extrusion process was utilized. This work addresses both, the simulative design as well as the implementation of heating and forming processes for BC extrusion. The joint interface of the hybrid components was analysed and a qualitative evaluation was carried out using metallographic images. The simulation results were validated and an effect on the joining zone trough BC extrusion could be achieved.
